Question:
1) The principle which allows a rainbow (multiplewavelengths bending) to form is
a. polarization
b. refraction
c.interference
d. diffraction
2) Refraction occurs
a. when light hits a solid nontransparent object
b. at any unpredictable time
c. only with sound waves
d. when a wave changes speed
3) The law of reflection says that
a. waves incident on a mirror are partially reflected
b. the angle of reflection from a mirror equals the angle ofincidence
c. all waves incident on a mirror are reflected
d. the angle a ray is reflected from a mirror is random
4) What happens if you took the original double slitexperiment and increased the distance of the slits to the wall(Length L)?
a. Diffraction bands Increases
b. Diffraction bands stay the same
c. Diffraction bands decreases
5) What occurs when a crest and a trough meet?
a. Destructive interference, bright bands
b. Constructive interference, dark bands
c. Constructive interference, bright bands
d. Destructive interference, dark bands
6) You can hear people around a corner but you can’t seethem because light waves
a. are much shorter than sound
b. travel much faster than sound
c. are much longer than sound
d. do not diffract
7) What principle is the reason for alternating lightand dark bands when light passes through two or more narrowslits?
a. diffraction
b. refraction
c. interference
d. polarization
8) In 2-4 sentences - Explain why, when a beam of lightshines through two tiny slits, there is a pattern of points ofintense light on a screen located on the other side of thepoint. Use and highlight at least 3 keyterms: interference, constructive, destructive, peaks, trough, brightbands, diffraction
