- JUST NEED HELP WITH D-J! A large container holds two layers of liquid: a 10.0 cm thick layer of vegetable oil (ρ = 920 kg/m3 , n = 1.47) above a 20.0 cm thick layer of water (ρ = 1000 kg/m3 , n = 1.33). There is air (ρ = 1.20 kg/m3 , n = 1.0003) above the oil layer. Nia holds a red laser which emits 632.8 nm light to the right and down, so that the ray makes an angle of 50.0° relative to a line normal to the oil layer. a) Draw a diagram showing the layers of liquid and the path of a light ray. At each interface between media, there should be a reflected ray and a refracted ray unless there is total internal reflection at that interface (in which case write N/A for the angle of refraction). Label the angles of each ray (incident, reflected, and refracted) for each interface. b) What is the angle of reflection at the air→ oil interface? ________________________ c) What is the angle of refraction at the air→ oil interface? ________________________ d) What is the angle of incidence at the…A ray path is passing through the interface between Layer 1 and Layer 2 withincident angle 45 degree.
