Question

The student uses a lens of focal length 50 cm and understood and uses the lens of -15 discuss the nature and find the power

Answer 1

Answer:

, we must first convert the focal length to meters; then, we substitute this value into the equation for power.

Answer 2

Hola mate!! here is ur ans':

First convert the focal length into metres

1m=100cm,

50cm=50/100m

F=1/2m or 0.5m

Power =1/f

=1/1/2

=1×2

=2D(dioptre) //

Hence proved.. itz virtual & erect..
