Hi.
00:01
Here in this given problem we have to find the statement which is incorrect.
00:06
So we look at all the statements one by one.
00:11
Statement a.
00:13
Here it looks to be correct because it is correct to say that in diffused reflection some of the rays may be parallel.
00:40
It will depend upon the nature of the surface.
00:51
Some of the reflected rays may be parallel.
01:10
Then we'll look at the second statement.
01:14
Reflection from a rough surface is diffused.
01:18
Yes, this is correct.
01:22
The second statement is absolutely correct.
01:25
Then the third one, reflection by smooth surfaces is specular.
01:30
Yes, that is also correct.
01:31
Because a regular reflection that is also known as specular reflection...
