... Not C or D: The light may be brighter or dimmer depending on the power of the light source. Note: It will probably appear to be brighter, because the light sources will be of similar power, but our eyes are more sensitive to green light. It’s either A or B: To answer this they have to remember what ...

Electromagnetic Waves
... Constructive interference occurs when the two waves have a relative phase difference of 0°. Since the two waves are emitted in phase, any phase difference must be due to the different distances the waves travel to reach the various points on the screen. For their phase difference to be 0°, their pat ...
