Answer:
[tex]\lambda=2.2x10^{-4}m[/tex]
Explanation:
Hello!
In this case, since the relationship between energy and wavelength is defined via the speed of light and the Planck's constant as shown below:
[tex]e=\frac{c*h}{\lambda}[/tex]
Since c stands for the speed of light and h for the so-called Planck's constant, we can compute the wavelength as follows:
[tex]\lambda=\frac{c*h}{e}=\frac{3.0x10^8m/s*6.626x10^{-34}J*s}{9.2x10^{-22}J}\\\\\lambda=2.2x10^{-4}m[/tex]
Best regards!
