AIM
To trace the path of a ray of light passing through a rectangular glass slab for different angles of incidence. Measure the angle of incidence, the angle of refraction, the angle of emergence and interpret the result.
What is refraction ?
During refraction what happens to speed , wavelength and frequency of the wave?
When travelling from a rarer medium to denser medium , the ray will bend on which reaction ?
When a ray of light travels from a denser medium to rarer, where the light will move in respect to normal?
What are the laws of refraction?
What is Snell's law?
What factors does the refractive index of a medium depend?
What is the unit of the refractive index?
What happen to the emergent angle on increasing the incident angle at the air-glass interface?
What is lateral displacement?
State the condition when no refraction occurs?
Why do you measure the perpendicular distance?
Why should the pins be fixed at least 4 to 6 cm apart?
How does the reflection of light different from refraction?
