  2. diffraction

  3. interference

  4. polarisation

A Correct answer
Explanation

Refraction

According to newton, when corpuscles approach the refracting surface , they are attracted near the surface. When they enter the denser medium from a rarer medium, their speed increases and hence change their direction.

Multiple choice physics light and shadow substances which allow light to pass through and those which do not transparent, opaque and translucent objects shadows

State whether true or false.

  1. True

  2. False

Multiple choice physics light and shadow substances which allow light to pass through and those which do not transparent, opaque and translucent objects shadows

Transparent objects.

  1. do not let light to pass through them

  2. allow light to pass through them

  3. absorb some amount of light and allow the remaining to pass through them

  4. reflect all the amount of light falling on them
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Transparent objects allow light to pass through them. These are objects having the property of transmitting light without any appreciable scattering so that the bodies lying beyond it are seen clearly.
