Question

in which three ways does the pattern seen on the screen during a double - slit experiment support the wave model of light?
a. there are bands of brighter light.
b. the light bends around the edges of the slit.
c. all of the light that enters the slits passes through them.
d. there are bands of dimmer light.

Explanation:

• A: Bright bands are due to constructive interference (a wave - like property).
• B: Bending (diffraction) is a wave - like phenomenon.
• D: Dimmer bands are due to destructive interference (a wave - like property).
• C: Does not support the wave model as it is a property that could also be associated with a particle - like view (if we consider light as particles passing through slits without any wave - related interaction).

Answer:

A. There are bands of brighter light, B. The light bends around the edges of the slit, D. There are bands of dimmer light.
