Question

In electromagnetic waves, frequency is inversely proportional to
A: Amplitude
B: Wave Speed
C: Wavelength
D: Reflection

Answer 1

Frequency is inversely proportional to wavelength.

Wavelength is the spacial period, and more generally the frequency is inversely proportional to the period.

If the wave's speed if c, then f=c/l where l is the wavelength.

Answer 2

In electromagnetic waves, frequency is inversely proportional to C. Wavelength.
