`A` sodium street light gives off yellow light that has a wavelength of `589nm`. What is the frequency of this light?

Text Solution

Verified by Experts

We known that `v=(C)/(lambda)=((3xx10^(8)ms^(-1)))/((589xx10^(9)m))=5.093xx10^(-14)s^(-1)`

The light-blue glow given off by mercury street-lamps has a wavelength of 436 nm . What is its frequency in hertz? Strategy: We given a wavelength and need to find the frequency. Wavelength and frequency are inversely related by the equation lambdav = c , which can be solved for v . Remember to convert lambda from nanometers to meters.
