Answer:

$1.99\cdot 10^(-25) J$

Step-by-step explanation:

Electromagnetic waves are oscillations of the electric and the magnetic field in a plane perpendicular to the direction of motion the wave.

All electromagnetic waves travel in a vacuum always at the same speed, the speed of light:

$c=3.0\cdot 10^8 m/s$

The energy of an electromagnetic wave is given by the equation:

$E=(hc)/(\lambda)$

where:

$h=6.63\cdot 10^(-34)Js$ is the Planck constant

$c=3.0\cdot 10^8 m/s$ is the speed of light

$\lambda$ is the wavelength of the wave

In this problem, we have a wave with wavelength of

$\lambda=1 m$

So, its energy is:

$E=((6.63\cdot 10^(-34))(3.0\cdot 10^8))/(1)=1.99\cdot 10^(-25) J$
