Light travels faster in air than that in glass. This is accordance with

  • wave theory of light

  • corpuscular theory of light

  • neigther (a) nor (b)

  • Both (a) and (b)

Solution

A.

wave theory of light

Light's speed in vaccum is the fastest it can go. However in air and glass photons occasionally bounce off other particles so the photons do not travel in a straight line; they have travel further than they would in vacuum so they appear to travel slower.

 Wave theory of light predicted that light could reflect off shiny surfaces, react or bend when moving from the material into another, and diffract (or spread ) around objects or moving through slits.

Light travels faster in air than that in glass. This is accordance with wave theory of light.

Why are infra-red waves often called heat waves? Explain.

What do you understand by the statement, 'Electromagnetic waves transport momentum'?

Wave property of electrons implies that they will show diffraction effects. Davisson and Germer demonstrated this by diffracting electrons from crystals. The law governing the diffraction from a crystal is obtained by requiring that electron waves reflected from the planes of atoms in a crystal interfere constructively (see in the figure).



If a strong diffraction peak is observed when electrons are incident at an angle ‘i’ from the normal to the crystal planes with distance’ between them (see figure), de Broglie wavelength λdB of electrons can be calculated by the relationship (n is an integer)

In an experiment, electrons are made to pass through a narrow slit of width’ comparable to their de Broglie wavelength. They are detected on a screen at a distance ‘D’ from the slit (see figure). 

Which of the following graph can be expected to represent the number of electrons ‘N’ detected as a function of the detector position ‘y’(y = 0 corresponds to the middle of the slit)?
