Question

Identify the object which produce light energy

(i) Torch light (ii) Stone (iii) Book (iv) Glowing bulb​

Answer 1

Answer:

Answer is (i) and (iv)

But more suitably, we can say (iv) as it is mentioned it is glowing and we don't know whether the torch light is on,

Just a guess

Answer 2

Answer:

None of them could produce light energy of its own,

the cells in torch light produces energy and the same happens in the glowing bulb.
