What is the wavelength (angstroms) of a photon that has an energy of 5.69 × 10-17 j?

The correct answer is .

Explanation:

The expression for the relation between the energy of the wave and the wavelength is as follows;

Here, E is the energy of the wave, h is Planck's constant, c is the speed of the light and is the wavelength of the wave.

It is given in the problem that the energy of the photon is .

Put c= , and

Convert the value of the wavelength into angstrom.

Therefore, the wavelength of a photon is .
