Alight beam travels at 1.94×108 in quartz. the wavelength of the light in quartz is 355 .part awhat is the index of refraction of quartz at this wavelength? part bif this same light travels through air, what is its wavelength there?

A) 1.55

The speed of light in a medium is given by:

where

is the speed of light in a vacuum

n is the refractive index of the material

In this problem, the speed of light in quartz is

So we can re-arrange the previous formula to find n, the index of refraction of quartz:

B) 550.3 nm

The relationship between the wavelength of the light in air and in quartz is

where

is the wavelenght in quartz

is the wavelength in air

n is the refractive index

For the light in this problem, we have

Therefore, we can re-arrange the equation to find , the wavelength in air:

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
