State the Snell's laws of refraction of light.

(a) State Snell's law of refraction of light. (b) A transparent medium A floats on another transparent medium B. When a ray of light travels obliquely from A into B, the refracted ray bends away from from the normal. Which of these two media A or B are optically denser and why ?

State the laws of refraction of light. State at least three examples of refraction of light.

State the laws of refraction of light. Explain the term 'absolute refractive index of a medium' and write an expression to relate it with the speed of light in vacuum.

State laws of reflection of light.

On the basis of Huygen.s wave theory, prove Snell.s law of refraction of light. Draw a neat and labelled diagram. (Postulates of Huygen.s wave theory not required)

State the two laws of reflection of light.

Huygen.s principle of secondary wavelets can be used to a) deduce the laws of rectraction of light b) deduce the laws of refraction of light c) explain the transverse nature of light waves d) predict the location of a wavefront as time passes

State Mendel's law of segregation.

What is the cause of refraction of light?
