What is a spectrum?
Name a prism required for obtaining a spectrum of Ultraviolet light.
Draw diagrams to show the refraction of light from
- air to glass, and
- glass to air. In each diagram, label the incident ray, refracted ray, the angle of incidence
- and the angle of refraction (r).
When light travels from a rarer to a denser medium, its speed ______.
A ray of light passes from water to air. How does the speed of light change?
The refractive index of air with respect to glass is defined: as gµa = sin i/sin r
If r = 90°, what is the corresponding angle i called?
Complete the ray diagram showing its emergence into the air after passing through the prism.
The velocity of light in diamond is 121000 kms-1. What is its refractive index?
Draw the ray diagram of a glass slab having medium A and B for the velocity of light ray VA and VB respectively and define Snell's law.
- If VB = 1.5 VA, then which medium is denser?
- What is the refractive index of A with respect to B?
- What is the refractive index of B with respect to A?
Observe the figure and name the ray AB, ray CD, ray GH.
