why should the wavelength scale of spectroscope be calibrated
Your spectroscope must be calibrated in order to account for systematic inaccuracy. The helium discharge tube is a handy source of emission lines.
Why is it necessary to calibrate the spectroscope's wavelength?Spectrometers will inevitably drift over time as a result of impacts and effects from the environment. Regular wavelength calibration, which helps to assure accurate and dependable spectroscopic data, can readily address this prevalent problem. The wavelength calibration verifies that the grating's angular position setting and the wavelengths assigned to each pixel on the CCD array detector are correct. By analysing the spectra of an orange glass and a suspension of microalgae, the process is demonstrated.
This is accomplished by comparing the wavelengths you empirically determined to wavelengths discovered via research in the literature.

An object has a charge of -1.6x10-13C, and object B is electrically neutral. Two million electrons are removed from A and placed on B. Expressed in coulombs, what is the resulting charge (algebraic sign and magnitude) on A and on B? (step by step explanation please)
The resulting charge on A is [tex]1.6 x 10^-7[/tex] C, and the resulting charge on B is [tex]-3.2 x 10^-7[/tex] C.
What do you mean by charge?A charge is a property of matter that results from the presence or absence of electrons. It can be either positive or negative, and two objects with opposite charges will be attracted to each other, while two objects with the same charge will repel each other. The unit of charge is the Coulomb (C), which is defined as the amount of charge carried by 6.242 x 10^18 electrons. The concept of charge is important in many areas of physics, including electricity and magnetism, and plays a role in many natural phenomena and technological applications.
The charge on object A is [tex]-1.6 X10^-13[/tex]C.
When two million electrons are removed from object A, the charge on object A becomes more negative. The charge on object A can be calculated using the formula:
Q = Q - ne,
where Q is the original charge, n is the number of electrons, and e is the charge of an electron, which is -1.6 x 10^-19 C.
Therefore, the charge on object A becomes:
[tex]Q = -1.6 X 10^-13 C - (2X10^6)(-1.6X 10^-19 C)[/tex]
[tex]= -1.6 X 10^-13 C + 3.2X 10^-7 C[/tex]
= 1.6 x 10^-7 C
Object B starts as electrically neutral, which means that the total charge on B is 0 C. When two million electrons are placed on object B, the charge on object B becomes more negative. The charge on object B can be calculated using the formula:
Q = Q + ne,
where Q is the original charge, n is the number of electrons, and e is the charge of an electron, which is -1.6 x 10^-19 C.
Therefore, the charge on object B becomes:
Q = 0 C + (2 x 10^6)(-1.6 x 10^-19 C)
[tex]= -3.2 X 10^-7 C.[/tex]
So, the resulting charge on A is[tex]1.6 X 10^-7[/tex]C, and the resulting charge on B is [tex]-3.2X 10^-7[/tex] C.

The formula vw=f⋅λ describes the relationship between the speed of a wave (vw), and its frequency (f) and wavelength (λ)
Yes, the formula mentioned is correct.
The formula vw = f * λ describes the relationship between the speed of a wave, its frequency, and its wavelength. In this formula:
vw = speed of the wave (m/s)
f = frequency of the wave (Hz)
λ = wavelength of the wave (m)
Wavelength is a term used in physics to describe the distance between two consecutive points on a wave that is in phase with each other. It is an important parameter that characterizes a wave and can help describe its behavior and properties.
The wavelength of a wave determines its size, shape, and behavior in a medium. For example, long-wavelength waves (such as radio waves) can penetrate solid objects, while short-wavelength waves (such as gamma rays) are absorbed by solid objects.
This relationship can be derived from the definition of wave velocity, which is the speed at which a disturbance travels through a medium. The frequency of a wave is defined as the number of complete cycles of the wave that pass a given point in one second, while the wavelength is the distance between two consecutive points on a wave that is in phase with each other.
The formula vw = f * λ shows that the speed of a wave is directly proportional to its frequency and inversely proportional to its wavelength.

Three identical container P, Q and R are taken, and kept - one on the terrace of a tall building; another on the terrace of a horter building; and the third in an open pace. After a rain, which one will have the highet level of water, auming no overflow and no obtruction near the container?
The container kept on the terrace of the taller building will have the highest level of water.
What is atmospheric pressure ?The level of water in a container depends on atmospheric pressure, and the atmospheric pressure decreases with height.
Atmospheric pressure, also known as air pressure, is the force exerted by the weight of air molecules in the atmosphere. It is measured in units of force per unit of area, typically in kilopascals (kPa) or pounds per square inch (psi).
Atmospheric pressure decreases with increasing altitude, as there are fewer air molecules above the earth's surface. At sea level, the average atmospheric pressure is approximately 101.3 kPa (14.7 psi), while at high elevations it can be significantly lower.
The taller building is higher up, so the atmospheric pressure on its terrace is lower than that at ground level, resulting in a lower water level in the container kept there.
The water level in the container kept on the terrace of the shorter building and the one kept in an open space will be at the same height, as they are both at ground level and have the same atmospheric pressure.
Therefore, The container kept on the terrace of the taller building will have the highest level of water.

A positive object touches a neutral electroscope, and the leaves separate. Then a negative object is brought near the electroscope, but does not touch it. What happens to the leaves?.
The leaves are getting closer.
An electroscope is an early scientific instrument used to detect the presence of electrical charges in a body. The charge is detected from the motion of the test object due to the Coulombic electrostatic force acting on the test object. The amount of electric charge on an object is proportional to the voltage. The electroscope consists of a metal button and he two blades. When a negatively charged object is brought close to the instrument, the blade will repel and move away. There are two types of electroscopes: the medulla electroscope and the gold foil electroscope. When a negatively charged object is brought close to the electroscope, the charge induces a positive charge on the leaves. So nothing should happen. However, induction causes the leaves to move closer together.
