The angle of incidence and the angle of reflection are equal
The correct option for the angle between the given light ray and the reflected ray is the option;
120°
Reason:
The given parameter are;
The angle formed by the light ray and the glass surface = 30°
Required:
To find the angle between the light ray and the reflected ray
Solution:
According to the laws of reflection, the angle between the incident ray and the normal is equal to the angle made between the reflected ray and the normal
The angle made between the incident ray and the normal, [tex]\theta _i[/tex] = 90° - 30° = 60°
Therefore, according to the laws of reflection, we have;
The angle made between the reflected ray and the normal, [tex]\theta _r[/tex] = The angle between the incident ray and the normal, [tex]\theta _i[/tex] = 60°
The angle made between the reflected ray and the normal, [tex]\theta _r[/tex] = 60°
The angle between the given light ray and reflected ray, θ = [tex]\theta _i[/tex] + [tex]\theta _r[/tex]
∴ θ = 60° + 60° = 120°
The angle between the given light ray and the reflected ray, θ = 120°
