A ray of light in air with a wavelength of 600 nm is incident on a liquid with an index of refraction of 1.5. The ray of light makes an angle of 45 degrees with the normal when it enters the liquid. What is the wavelength of the ray of light in the liquid?
A small block of mass m = 1.5 kg slides, without friction, along the loop-the-loop track shown. the block starts from the point P a distance h = 54 m above the bottom of the loop of radius R = 17.0 m. What is the kinetic energy of the mass at the ..
