The magnetic component of a polarized wave of light is given by Bx = (4.00 µT) sin [ky + (2.00 x 10^15 s-1) t].
(a) what is its intensity?
(b) Write an expression for the electric field of the wave, including a value for the angular wave number.
(c) What is the wavelength?
(d) In which region of the electromagnetic spectrum is this electromagnetic wave?
Some people will pay a higher price for brand-name goods. For example, some people buy Rolls-Royces and Rolex watches to impress others. Does knowingly paying higher prices for certain items just to be a "snob" violate the law of demand?
A u-tube with constant cross section is partly filled with water. Engine oil of density 0.8g/cm3 is poured into the right arm (without mixing) until the water level rises 2.0cm. The length of the oil column is then.
