Question

Collectively, ________ and ________ tell us how much energy is stored inside a wave.

Answer 1

frequency and wavelength

If the wavelength is given, the energy can be determined by first using the wave equation (c = λ × ν) to find the frequency, then using Planck's equation to calculate energy.

Planck's equation
E = hν


h = 6.63 × 10 -34 J·s
c = 3.00 × 10 8 m/s
v = frequency (Hz)
