An AM radio station uses radio waves with wavelengths of 300 meters. How much energy is in this wave? 1.7 x 10-24 J

E = 6.6×10⁻²⁸ J

Explanation:

Given data:

Wavelength = 300 m

Energy of wave = ?

Solution:

Formula:

E = h c/λ

c = 3×10⁸ m/s

h = 6.63×10⁻³⁴ Js

Now we will put the values in formula.

E = 6.63×10⁻³⁴ Js × 3×10⁸ m/s / 300 m

E = 19.89×10⁻²⁶ J.m / 300 m

E = 0.066×10⁻²⁶ J

E = 6.6×10⁻²⁸ J
