What happens to the diffraction pattern when the number of lines per centimeter?

What happens to the diffraction pattern when the number of lines per centimeter of a diffraction grating is increased? An identical diffraction pattern can be created by using light of a longer wavelength.

What happens when you increase the distance between slits in a diffraction grating?

If the distance between slits is increased far enough you get something like a picket fence, and the diffraction pattern would be like the shadow of a picket fence. What happens in between is that as the spacing is increased the bands get closer together and eventually merge to form an image of the grating.

What happens when number of slits increases?

As the number of slits is increased, the intensity of the principal maxima increases and the width decreases.

How does the number of lines or slits in a diffraction grating affect the resolution of interference maxima?

Maxima can be produced at the same angles, but those for the diffraction grating are narrower and hence sharper. The maxima become narrower and the regions between darker as the number of slits is increased.

What is the effect on diffraction pattern if the number of lines on the grating is decreased?

The principal maxima become more sharp and intense. Thus, a theoretical limit is reached the first order maximum will not be visible. If (a+b) <λ sinθ becomes greater than 1, which is not possible. Hence no spectrum is formed and the grating is rendered useless.

What happens when white light passes through a diffraction grating?

White light can be separated into all seven major colors of the complete spectrum or rainbow by using a diffraction grating or a prism. The diffraction grating separates light into colors as the light passes through the many fine slits of the grating.

What happens to the diffraction pattern when the distance between slits within?

When the distance between slits within the grating is increased, bands get closer together and eventually merge to form an image of the grating.

Would you expect the number of fringes to increase or decrease as you increase the number of slits?

The intensity of the fringes produced by the interference of light from the slits is modulated by the diffraction pattern produced by each of the slits. That is why the intensity of the interference fringes deceases as the order of the fringes increases.

How does the width of the slits affect the intensity in diffraction?

When the widths of the slits are greater than the wavelength of the light, the light casts the shadow. When the widths of the slits are narrow, light undergoes diffraction and the light waves overlap on the screen. Hence, the intensity of the light is more as the width of the slit increases.

How many lines per centimeter does the grating have?

Since there are 10,000 lines per centimeter, each line is separated by 1/10,000 of a centimeter.

How does the number of slits affect a diffraction grating?

Increasing the number of slits not only makes the diffraction maximum sharper, but also much more intense. As the intensity increases, the diffraction maximum becomes narrower as well as more intense.
