Question

If two similar flashlights shine on a wall from the same distance, the spot on the wall becomes brighter. This is due to light wave _______________. A) absorption B) diffraction C) constructive interference D) destructive interference

Answer 1

It is constructive interference! Constructive interference is when two light waves basically combine two make a taller or lower wave with the same amplitude!

Answer 2

C) constructive interference

Step-by-step explanation:

• The flashlights that shine in the wall form the same distance and the spot on the wall becomes brighter is due to the wavelength of the two waves.

• The clashes simultaneously on the same direction and with the same intensity and distance thus creating a more bigger impact. And is said to have a high frequency due to their interaction.
