The greater the frequency of an em wave, the its energy.
a. smaller
b. not enough info
c. same
d. greater

The greater the frequency of an EM wave, the greater its energy.

Explanation:

The energy and frequency are directly related to each other.

The higher the frequency the greater will be the energy of wave.

Mathematical relationship:

E = h.f

E = energy

h = planck's constant

f = frequency

While wavelength and energy are inversely related to each other.

The wave with lowest wavelength have higher energy.

The above expression can be written as,

E = h.f

f = c/λ

E = h. c/ λ.

i just learnt this recently but i need to look through my notes again
