Light with wavelength 503 nm passes through crystalline sodium chloride. (The index of refraction of sodium chloride is 1.544.) (a) Find the speed of light in this medium. v = m/s
(b) Find the wavelength of the light. λn = nm
(c) Find the frequency of the light. f = Hz

The speed of light in a material is 0.50 c. what is the critical angle of a light ray at the interface between the material and a vacuum?

What is the stall speed at sea level of an airplane that weights 10000 lbs., has a wing area of 300ft^2, and a maximum lift coefficient of 1.4? what is the stall speed if flaps that double cl,max are applied?

Automobile fuel efficiency is often measured in miles that the car can be driven per gallon of fuel (mpg). heavier cars tend to have lower fuel efficiencies (lower mpg ratings). which variable (weight or fuel efficiency) is most naturally considered the explanatory (predictor) variable in this context?
