A tiny layer of oil (n = 1.25) is situated on top of a water puddle (n = 1.33) in a parking lot. If the thickness of the oil is 242 nm, the what color(s) of visible light will give a strong reflection?
2t=m*lambda/n2
2t=242nm/1.25 and then 2t=242nm/1.33
i just don't know what goes where...

hi I am new and new to physics i am have a lot of trouble with this problem
mass =1.3kg
41.5J
how do i get the velocity
so far i have it wrote like this
41.5J=1/2(1.3kg)(v)^2
but don't know how else to do please help thanks ron
