Chapter 12, Problem 1STP

To determine

To choose: The correct option.

Answer to Problem 1STP

Option (B) is correct answer.

Explanation of Solution

Introduction:

The type of wave carrying energy through matter and/or space is known as light. Light waves carry radiant energy. Any device used for irradiation, illumination, projection or signaling is known as lighting device.

Opaque material absorbs and also, reflects light; and because of this a person cannot see object through it. Translucent materials transmit light and also absorb it (or scatter it). Transparent material transmits light without absorbing it and because of this a person can see object clearly through transparent material.

So, the correct option is (B).

Option (A) is incorrect because through it light does not transmit completely.

Option (C) is incorrect because through it light does not transmit.

Option (D) is incorrect because through it light does not transmit.

Conclusion:

The word “transparent” describes the materials which transmit light so the object behind them can be seen clearly. Correct option is (B)
