- A light ray is incident on the surface of a sphere of refractive index n at an angle of incidence \(\theta_0\). The ray partially refracts into the sphere with angle of refraction \(\phi\) and then partly reflects from the back surface. The reflected ray then emerges out of the sphere after a partial refraction. The total angle of deviation of the emergent ray with respect to the incident ray is \(a\). Match the quantities mentioned in List-I with their values in List-II and choose the correct option.
List-I List-II P If \(n = 2\) and \(\alpha = 180°\), then all the possible values of \(\theta_0\) will be I \(30\degree\) or \(0\degree\) Q If \(n = √3\) and \(\alpha= 180°\), then all the possible values of \(\theta_0\) will be II \(60\degree\) or \(0\degree\) R If \(n = √3\) and \(\alpha= 180°\), then all the possible values of \(\phi_0\) will be III \(45\degree\) or \( 0\degree\) S If \(n = \sqrt2\) and \(\theta_0 = 45°\), then all the possible values of \(\alpha\) will be IV \(150\degree\) \[0\degree\] - JEE Advanced - 2024

Reflection of Light
When a light ray falls on any object, it is bounced back from the object. This process is known as the Reflection of light. The light reflected from the object falls into our eyes, making the object visible to us. All the things we see around us are because of reflection.
The reflection of light depends on the type of object. A polished or smooth surface reflects most of the light falling on it, while a rough surface absorbs some amount of light and reflects back the rest of the light. The direction of reflected rays depends upon the surface of the object.
