select the correct answer.
if a light wave is reflected from the surface of the medium, which property of the light wave will change with the reflected wave?
a. amplitude
b. wavelength
c. frequency
d. speed

Explanation:

• For light reflection: Frequency is determined by the source, so it remains unchanged. Wavelength and speed depend on the medium; during reflection, the light wave stays in the same medium (before and after reflection, the incident and reflected waves are in the same medium for the part relevant to reflection properties), so wavelength and speed don't change. Amplitude can change because some energy might be absorbed or scattered at the surface, affecting the amplitude of the reflected wave.

Answer:

A. amplitude
