Question

Electromagnetic radiation travels in waves. waves have energy. what is the relationship between the wavelength of electromagnetic radiation and the energy of the wave

Answer 1

Electromagnetic radiation consists of many photons, each photon carrying an energy of
$E=hf$
where
$h=6.6 \cdot 10^{-34} Js$ is the Planck constant
f is the frequency of the wave.

We also know a relationship between frequency and wavelength of a wave:
$f= \frac{c}{\lambda}$
where
$c=3 \cdot 10^8 m/s$ is the speed of light
$\lambda$ is the wavelength.

Substituting the second equation into the first one, we find a relationship between the energy of a wave and its wavelength:
$E=h \frac{c}{\lambda}$

Answer 2

The relation between the wavelength of electromagnetic radiation will be   $E=\dfrac{hc}{\lambda}$

What is Electromagnetic wave?

Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field.

Electromagnetic radiation consists of many photons, each photon carrying an energy of

$E=hf$

where $h=6.6\times 10^{-34}$

is the Planck constant

f is the frequency of the wave.

We also know a relationship between frequency and wavelength of a wave:

$f=\dfrac{c}{\lambda}$

where$c=3.8\times 10^{8} m/s$

is the speed of light

is the wavelength.

Substituting the second equation into the first one, we find a relationship between the energy of a wave and its wavelength:

$E=\dfrac{hc}{\lambda}$
