Questions Related to substances which allow light to pass through and those which do not

State whether true or false.
Opaque objects allow light to pass through them.

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

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Transparent objects allow the light to pass through them whereas opaque objects doesn't allow any light ray to pass through them.

State whether true or false:
You can clearly see through a blue-tinted drinking glass.

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

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

No since the dispersion of light occurs when we observe things through the blue tinted drinking glass so objects are not so clear.

State whether true or false:
Wood is an example of opaque object.

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

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

Since opaque object are objects which doesn't allow any light ray to pass through it and we cannot see through it. For example wood.

In ........................... lens, all the rays diverge after refraction.

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

  1. Concave

  2. Bi-concave

  3. Convex

  4. Bi-convex

Show answer
Correct Option: A

An object is transparent if you can see through it clearly.

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

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

A transparent substance is defined as the substance through which all light incident on it normally can pass through it.And hence , it can be seen clearly through a transparent substance.


Given statement is $True$.

You can clearly see through a blue-tinted drinking glass.

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

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Its a translucent object. light partially passes through it.

Wood is an example of opaque object.

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

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

No light passes through opaque objects and we can't see through these objects.

For example, wood.

You can clearly see through opaque objects.

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

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

It is false that you can clearly see through opaque objects as objects which are seen through are transparent and object which does not allow any light to pass through it are opaque.

Which of the following is transparent?

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

  1. Stone

  2. Wood

  3. Plastic

  4. Glass

Show answer
Correct Option: D
Explanation:

A transparent object is one which allows all light to pass through it.
Since glass allows all the light to pass through it, so it is a transparent object.

Stone, wood and plastic are opaque materials.

Which of the following is an opaque object?

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

  1. Wood

  2. Glass

  3. Air

  4. Vacuum

Show answer
Correct Option: A
Explanation:
Wood being an opaque object, does not allow light to pass through it.
All other objects allow light to pass through it.
