So in the first part of the question, the question says that there is an object, and under white light, it appears cyan, right? sign color.
00:16
Now, the question asks us to find under red light, which color is it likely possible to be? now we know that cyan is a mixture of green and blue.
00:34
So in this scenario the object is reflecting sign that means this is getting reflected as well as this so green and blue is getting reflected everything else everything else is getting absorbed right so when red light falls it gets absorbed so since there's nothing left it gets absorbed so since there's nothing left therefore object is black black in color.

Okay, this is the answer for the first part of the question.
01:46
Okay.
01:47
Now, the second part of the question says, second part of the question says, when sign light is made to fall on the object.
02:10
So this is sign light, right? blue light is reflected.
02:19
Now, sign consists of green as a well as blue.
02:29
Now this is reflected and this is absorbed...
