The formula relating wavelength and frequency is:
f = c / ʎ
where f is frequency, c is speed of light = 3 x 10^8 m/s,
and ʎ is wavelength of light = 2.76 x 10^-7 m
f = (3 x 10^8 m/s) / 2.76 x 10^-7 m
f = 1.09 x 10^15 s-
The energy can be calculated using the formula:
E = h f
where h is Planck’s constant = 6.626 x 10^-34 J s
E = (6.626 x 10^-34 J s) * 1.09 x 10^15 s-
E = 7.2 x 10^-19 J
