Answer 1

Answer #1

Energy of the photons = hc / $\lambda$

c - Speed of light

h - Planck's Constant

$\lambda$ - Wavelength of light

8.04 * 10^-19 = (6.626 * 10^-34 * 3 * 10⁸) / $\lambda$

$\lambda$ = 2.47 * 10^-⁷m

Energy = h * frequency

f = 8.04 * 10^-19 / 6.626 * 10^-34

f = 1.21 * 10¹⁵ Hz

Wavelength of the Photon = 2.47 * 10^-⁷m

Frequency of the Photon = 1.21 * 10¹⁵ Hz
