Properties of light that define light as a wave?

Are the properties:

Wavelength

Amplitude

Period

Frequency

Speed

OR

Reflection

Refraction

Dispersion

Diffraction

Interference

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

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.
