A light travels from air into water, the angle of refraction is `25^@` to the normal. Find the angle of incidence. Refractive index of water is 1.33 . `mu_a =1`

Text Solution

Verified by Experts

Given
`mu_(1) sin 1= mu_(2) sinr `
`mu_(a) sin I = mu_(w) sin r`
`mu_(a) =1 `
`mu_(w)=1.33`
`r=25'`
To find : Angle of incidence , i=?
`sin i=(mu_(w))/(mu_(a))`
`sin r=((1.33 xx sin 25^(@))/(1))`
Angle of incidence, `i=34.2^(@)`
