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 thin wedge filled with air is produced when two flat glass plates are placed on top of one another and a slip of paper is inserted between them at one edge. Interference fringes are observed when monochromatic light falling vertically on the plates are seen in reflection. Is the first fringe near the edge where the plates are in contact a bright fringe or a dark fringe? Explain.arrow_forwardAt what angle does a diffraction grating produce a second-order maximum for light having a first-order maximum at 20.0°?arrow_forwardIf a beam of white light passes through a diffraction grating with vertical lines, the light is dispersed into rainbow colors on the right and left. If a glass prism disperses white light to the right into a rainbow, how does the sequence of colors compare with that produced on the right by a diffraction grating?arrow_forward
- Is higher resolution obtained in a microscope with red or blue light? Explain your answer.arrow_forwardA 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_forwardShow that a diffraction grating cannot produce a second-order maximum for a given wavelength of light unless the first-order maximum is at an angle less than 30.0°.arrow_forward
