No. Of waves of orange light emitted by krypton in 1m is __________???
How to find this ???

Dear Student,

the length is 1 meter in total in which the orange light will be visible.

Wavelength of Kr 86 is known to be 605 nm (orange in visible region)

So number of wavelengths in 1 meter = 1/605 * 10^-9.

Number of Wavelengths = 1652892.562.

The number of wavelength will be 1652892.562
