Question

A block of white color is kept on a table. Suppose you are looking at this block through a glass which allows only red light to pass through it. What would be the color of the block as seen by you using the glass

Answer 1

Red only

Step-by-step explanation:

Answer 2

red

Step-by-step explanation:

The color of the block as seen by you using the glass would be red.

When white light passes through a red filter, only the red portion of the light is allowed to pass through. The other colors (blue, green, yellow, etc.) are absorbed by the filter. So, when you look at the white block through a red filter, you will only see the red portion of the light reflected off the block, making it appear red to your eye.
