Which colour of light has a higher critical angle? Red light or green light.
Can light be ‘piped’ like sound in a doctor’s stethoscope?
Complete the following diagram to show the path of the ray of a single colour in the diagram as if enters in and emerges out of the prism. Mark the angles wherever necessary. (Critical angle for glass = 42°).
Explain ‘mirage’ as an illustration of refraction.
The angle of minimum deviation produced by a thin glass prism in air is 'δ'. If that prism is immersed in water, the angle of minimum deviation will be ______.
( aμg = refractive index of glass w.r.t, air aμw = refractive index of water w.r.t. air)
For a ray of light, the critical angle is minimum when it travels from ______.
Total internal reflection can take place only if light is travelling from ______.
The entire light is reflected back into the denser medium is called ______.
A green light is incident from the water to the air-water interface at the critical angle (θ). Select the correct statement.
