## anonymous 3 years ago The wavelength of light in the infrared region is 4.257 x 10^-7 cm. What is the frequency of this light? Need to show work.

$\nu=\frac{ c }{ \lambda }$

How do you solve it? I've never seen that formula before...

lights velocity = 3 x 10*8 m/s frequency = v/w = 3 x 10*8/4.257 x 10*-7 = 7.05 x 10*14 Hz
