Adiver shines light up to the surface of a flat glass-bottomed boat at an angle of 30° relative to the normal. if the index of refraction of water and glass are 1.33 and 1.5, respectively, at what angle (in degrees) does the light leave the glass (relative to its normal)?

angle at which it will leave glass is 34.33 degree with normal

Explanation:

As per Snell's law we know that

here we have

= Angle of incidence

now from above formula we will have

so angle at which it will leave glass is 34.33 degree with normal

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
