Question

Properties of light that define light as a wave?

Are the properties:
Wavelength
Amplitude
Period
Frequency
Speed

OR

Reflection
Refraction
Dispersion
Diffraction
Interference

Answer 1

The first choices are correct, because the second choices could happen by things other than light.

Answer 2

I believe the correct answer from the two choices above is the first set of choice. Properties of light that define light as a wave are Wavelength,
Amplitude, Period, Frequency and speed. These terms are used and calculated to define a light as a wave. Hope this answers the question.
