Light is shining in the images. which object reflects a lot of light, absorbs a little light, and transmits almost no light?

The correct answer to the question is: Object B.

EXPLANATION:

Before going to answer this question, first we have to understand the reflection coefficient, transmission coefficient and absorption coefficient.

The reflection coefficient ( r )of an object is the ratio of energy reflected to the total energy incident on the object.

The absorption coefficient ( a )  of an object is defined as ratio of amount of energy absorbed to the amount of energy incident on it.

Similarly, the ratio of amount of energy transmitted to the total amount of energy incident is called transmission coefficient ( t ).

We know that a + r + t = 1

If a = 0 and t = 0, the reflection coefficient r = 1.

The body having reflection coefficient approximately equal to one will reflect a lot of light, absorbs a little light, and will transmit almost no light.

As per options given in the question, the body B is more polished and shining. Hence, its reflection coefficient is more as compared to transmission and absorption coefficient.

Hence, the answer of the question is object B.
