The speed of light in air is 3.0 x 10^8 m/s. the speed of light in particular glass is 2.3 x 10^8 m/s. use the information to determine the angle of refraction of light which travels from the glass into air, if the angle of incidence on the glass/air boundary is 25° . draw a diagram.

33.61°

Explanation:

Refractive index is equal to velocity of the light 'c' in empty space divided by the velocity 'v' in the substance.

Or ,

n = c/v.

v is the velocity in the medium  (2.3 × 10⁸ m/s)

c is the speed of light in air = 3.0 × 10⁸ m/s

So,  

n = 3.0 × 10⁸ /  2.3 × 10⁸

n = 1.31

Using Snell's law as:

Where,  

 is the angle of incidence  ( 25.0° )

is the angle of refraction  ( ? )

is the refractive index of the refraction medium  (air, n=1)

is the refractive index of the incidence medium (glass, n=1.31)

Hence,  

Angle of refraction = = 33.61°

terd muffin is the correct answer

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
