Hello everyone in this question we have to find the speed of light wavelength of light and angle of refraction in plexiglass the given parameters are the wavelength of green laser light is alpha 1 which is equal to 5 .30 multiplied by temperature to power minus the angle of incidence theta i is equals to 24 degree.
00:25
Repractive index of flexiglass angle is equal to 1 .5.
00:29
Now for the first part of the question, we have to calculate the speed of light, speed of light, that is v.
00:42
Now let's suppose that speed of light, speed of light or in plexiglass is, v, refractive index of any material is defined as ratio of speed of light in vacuum to the speed of light in material.
01:02
Therefore, refractive index of plexiglass is equal to speed of light, speed of light in vacuum, vacuum divided by speed of light in glass, therefore, an1 is equal to c by v, therefore v is equal to c divided by an1.

On putting the values, we have 3 multiplied by 10 to power 8, all divided by 1 .51.
01:41
Therefore it is equal to 1 .986 multiplied by 10 to power 8 meter per second.
01:51
Hence, it is also equivalent to 1 .99, 10 to power 8 meter per second, this is the heat of lyrine taxi glass...
