g A ray of light is incident on a flat reflecting surface and is reflected. If the incident ray makes an angle of 28.7° with the normal to the reflecting surface, what angle does the reflected ray make with the normal?

Answer:

[tex]\theta_2 = 15.8[/tex]degree

Explanation:

given data:

[tex]\theta_1 = 28.7 degree[/tex]

accoding to the snell's law

[tex]n_1*sin\theta_1=n_2*sin\theta_2[/tex]

where n1 is refracting index of air = 1

n2 is refracting index of glass = 1.55

putting all value to get angle mad by incident ray with normal

[tex]\theta_2 = \frac{1*sin28.7^{o}}{1.55}[/tex]

[tex]\theta_2 = 15.8[/tex]degree
