A glass plate 2.50 mm thick, with an index of refraction of 1.40, is placed between a source of light with wavelength 540 nm (in vacuum) and a screen. The source is 1.80 cm from the screen.

How many wavelengths are there between the source and the screen?

(HINT: the wavelength of light inside the glass is different!)

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator.
