Hi friend,
The angle of incidence must be9 0° to get maximum work done.
Reasons:-
W= F×s cos theta
Where cos90°=1
Therefore the anglWhat should be the angle of incidence in order to get minimum work done??e of incidence is equal the plane surface.
Hope this helped you a little!!!

saka82411:
Minimum is 90°
thank you so much!!
but dont you think it should be 180 degrees because cos 180 is equal to -1 which is less than 0 (cos 90)
i have a confusion in that
Work done can't be in negative
So you don't take worry of that
ohh i see
thanks a lot
Click on red heart thanks
okk baby lo thanks

The angle of incidence for a ray of light at a refracting surface of a prism is 45^o . The angle of prism is 60^o the ray suffers minimum deviation .
