Question

Calculate the energy of frequency 45MHz

Answer 1

4500000 is answer
i hope help ful for you

Answer 2

Energy , E = hf

where h is the Plank's Constant

= 6.62607004 × 10^-34m^2 kg / s

f is the frequency = 45MHz = 45×10^6 Hz

So, Energy = 6.62607004 × 10^-34m^2 kg / s × 45×10^6 Hz

=298.17 × 10^-28 J

= 2.9817 × 10^-26 J
