FAQs on Finding lateral shift and refractive index of glass slab : Std 10 Board Exam Practical Video Lecture - Class 10

1. What is lateral shift in the context of a glass slab?
Ans. Lateral shift refers to the displacement of a ray of light when it passes through a glass slab at an angle. It is the horizontal distance between the incident ray and the emergent ray.
2. How can we find the lateral shift of a glass slab experimentally?
Ans. The lateral shift of a glass slab can be found experimentally by using a setup consisting of a glass slab, a light source, and a screen. By measuring the distance between the incident ray and the emergent ray on the screen, the lateral shift can be determined.
3. What is the refractive index of a glass slab?
Ans. The refractive index of a glass slab is a measure of how much the speed of light is reduced when it passes through the slab. It is defined as the ratio of the speed of light in vacuum to the speed of light in the glass slab.
4. How can we calculate the refractive index of a glass slab?
Ans. The refractive index of a glass slab can be calculated by using the formula: Refractive index (n) = Speed of light in vacuum / Speed of light in glass slab. The speed of light in vacuum is a constant value, while the speed of light in the glass slab can be determined experimentally.
5. What factors can affect the lateral shift and refractive index of a glass slab?
Ans. The lateral shift and refractive index of a glass slab can be affected by various factors such as the angle of incidence, the thickness of the slab, and the refractive index of the surrounding medium. Changing any of these factors can result in different values for the lateral shift and refractive index.
