Which equation shows how wavelength is related to velocity and frequency? A. ? = V +f
B. 2 =
f
V
O C. 2=
D. 2 = vxf

The correct option is the option;

Explanation:

The wavelength of a wave is the distance between two successive crests of the wave

Therefore, the wavelength, λ, is given by the fraction of the velocity, v, of the wave divided by the frequency, f, (the number of cycles that pass through a point) of the wave

Mathematically, we have;

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
