A prism bends blue light more than red. Is the same true of a diffraction grating?
Whether a diffraction grating bends blue light more than red.
Answer to Problem 1FTD
In diffraction grating red lights bend more than blue light.
Explanation of Solution
The prism works because of refraction while diffraction grating works on the principle of diffraction. In refraction lower wavelength bends more than higher wavelength lights.
This is the reason why prism bends blue light more than red. However, in diffraction higher wavelengths bend more than lower wavelengths. Thus in diffraction grating red lights bends more than blue light.
Conclusion:
In diffraction grating red lights bend more than blue light.

- A beam of monochromatic green light is diffracted by a slit of width 0.550 mm. The diffraction pattern forms on a wall 2.06 m beyond the slit. The distance between the positions of zero intensity on both sides of the central bright fringe is 4.10 mm. Calculate the wavelength of the light.arrow_forwardA certain grade of crude oil has an index of refraction of 1.25. A ship accidentally spills 1.00 m3 of this oil into the ocean, and the oil spreads into a thin, uniform slick. 11 the Him produces a first-order maximum of light of wavelength 500 mm normally incident on it, how much surface area of the ocean does the oil slick cover?
