Question

A ray of light passes from air to glass (n=1.5) st an angle of 30 calculate the angle of refraction​

Answer 1

Answer:

angle of refraction=19.47 degree

Explanation:

n1sinθ1=n2sinθ2

WHERE

n1=refractive index of air

n2=refractive index of glass

sinθ1=sin30

θ2=angle of refracrion

SOLVE AS:

θ2=sin-1[(1*sin30)/1.5]

θ2=19.47
