Wavelength and Frequency Video Lessons

Concept: The Electromagnetic Spectrum

# Problem: A green laser pointer emits light with a wavelength of 533 nm. What is the frequency of this light?

###### FREE Expert Solution

Calculate frequency (ν):

$\overline{){\mathbf{c}}{\mathbf{=}}{\mathbf{\lambda }}{\mathbf{·}}{\mathbf{v}}}\phantom{\rule{0ex}{0ex}}\frac{\mathbf{c}}{\mathbf{\lambda }}\mathbf{=}\frac{\overline{)\mathbf{\lambda }}\mathbf{·}\mathbf{v}}{\overline{)\mathbf{\lambda }}}\phantom{\rule{0ex}{0ex}}\overline{){\mathbf{v}}{\mathbf{=}}\frac{\mathbf{c}}{\mathbf{\lambda }}}$
