White light is made of all colours of the visible spectrum which
has a wavelength range of approximately 380 – 750 nm (violet to
red). White light is incident on a diffraction grating that has 90
lines/mm. What is the width of the 1st order rainbow
band that appears in the diffraction pattern if the screen is 1.60
m away? Express your answer in mm and round to 2 decimal
places.

Visible light passes through a diffraction grating that has 900 slits per centimeter, and the interference pattern is observed on a screen that is 2.32 m from the grating. A) In the first-order spectrum, maxima for two different wavelengths are separated on the screen by 3.18 mm . What is the difference between these wavelengths? ___ m
11. A diffraction grating (multiple slits) with 3500 slits/em is illuminated with white light at normal incidence. The distance between the grating and the screen is 1.2 m. What is the gap on the screen between the first order visible spectrum and second order visible spectrum? 7% [Note that the angle between the central line and the line to the spectrum on the screen is not small] Answer:
White light containing wavelengths from 400 nm to 750 nm falls on a grating with 7500 lines/cm. How wide is the first-order spectrum on a screen 2.20 m away? ___m

White light is made of all colours of the visible spectrum which has a wavelength range of approximately 380 - 750 nm (violet to red). White light is incident on a diffraction grating that has 110 lines/mm. What is the width of the 1st order rainbow band that appears in the diffraction pattern if the screen is 1.50 m away? Express your answer in mm and round to 2 decimal places. Your Answer: Answer
White light (400 nm - 700 nm) diffraction pattern lights up a screen that is 3.60 m away. The diffraction grating has 503 slits per mm, which produces a rainbow of diffracted light. What is the width of the first order rainbow on the screen?
White light (400 nm - 700 nm) diffraction pattern lights up a screen that is 4.20 m away. The diffraction grating has 450. slits per mm, which produces a rainbow of diffracted light. What is the width of the first order rainbow on the screen?
