A grating 1
Subject:PhysicsPrice:3.86 Bought7
A grating 1.0 cm across has exactly 16000 slits. Orange light of 0.620 μm is incident on the grating creating a diffraction pattern on a screen that is 8.50 m away.
- What is the distance between adjacent slits on the grating?
- How many orders can be seen with the grating?
- What are the locations of constructive interference on the screen? (Give answers as the distance from the central bright spot in the diffraction pattern.)
- How does the pattern change if blue light (0.440 μm) is used instead of red?
