Follow these steps to solve this problem: A very thin oil film (noil=1.25) floats on water (nwater=1.33). What is the thinnest film that produces a strong reflection for green light with a wavelength of 500 nm?
1.Which of the following equations should be used to find the minimum thickness t of the oil film that satisfies the conditions of the problem? Let λ be the wavelength of light in air and n the index of refraction of the thin film
. a. 2t=mλn(m=0,1,2,...) for constructive interference.
b.2t=(m+12)λn(m=0,1,2,...) for destructive interference.
c.2t=(m+12)λn(m=0,1,2,...) for constructive interference.
d. 2t=mλn(m=0,1,2,...) for destructive interference.
2. What is the minimum (non-zero) thickness t of the film that produces a strong reflection for green light with a wavelength of 500 nm?

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
