Work Step by Step
The relationship between wavelength, frequency, and photon energy are as follows:
$v\lambda=c$
$E=hv$
$E=\frac{hc}{\lambda}$
This means that wavelength and frequency are inversely proportional, photon energy and frequency are directly proportional and photon energy and wavelength are inversely proportional.
The unit of $1$ Joule is $1\text{ J}=1\text{ kg}\cdot \text{m}^2/\text{s}^2$. A photon of energy $1$ J has enough energy to accelerate $1$ kg of mass at $1$ m/s$^2$ over $1$ meter.
