PHOTOELECTRIC EFFECT

Review 'Light in Chemistry'

Now with math:

New Light equations used in calculating energy or wavelength of light emitted (or absorbed) by atoms/molecules.

Equations:

1) E = hv

2) v = c/λ

E – energy h – Plank’s constant (6.626 x 10-34 J·s) v – frequency

c – speed of light (2.9979 x 108 m/s) λ - wavelength
