A beаm оf light trаvels frоm аir intо a glass block. In air, the light has a wavelength of 550 nm and a speed of 3.00 × 10⁸ m/s. Inside the glass, the speed of light decreases to 2.00 × 10⁸ m/s. a) What happens to the frequency of the light when it enters the glass? Explain. b) Calculate the new wavelength of the light inside the glass.
