A plane glass plate is placed over a various coloured letters ( violet , green , yellow , red ) . The letter which appears to raised more is

A

Red

B

Yellow

C

Green

D

Violet

Text Solution

Verified by Experts

The correct Answer is:
D

`S_(N)=t(1-(1)/(n))` As n increases, `(1)/(n)` decreases and `(1-(1)/(n))` increases.
`therefore SN` is more for that colour, for which n is more.
Among the given colours n is more for violet. Therefore it appears to be raised more.
