Answer 1

Answer:

pls mark me the brainliest

Explanation:

If the torch is covered with transparent paper and the beam sent through an opaque object, the opaque object since does not reflect light will only observe a kind of dark shadow behind the object,

Answer 2

• Torch is a Source of White Light.
• White Light passes through Transparent coloured paper, but the Light that comes out will be of the paper colour.
• Lets Assume that: You have covered the torch with transparent red coloured plastic paper.
• Light that comes out of the Torch is now Red-Light.
• When this falls on an opaque object, Light does not emerge through it. So, Light passes around the opaque object leaving a shadow of the opaque object on the screen that is kept beyond the object.
• What we can see is: Red coloured light passing around the shadow of the opaque object.
