State True/False for the following: a) Light is a form of electromagnetic radiation and travels with a speed of 3.0 x 10^10 cm/s in vacuum. b) A light wave of wavelength 589.0 nm travelling through air is incident on a smooth,flat slab of crown glass at an angle of 30.0 to the normal. Hence the corresponding angleof refraction is about 39.2. c) Light of wavelength 589.0 nm enters glass (n = 1.52). Hence the wavelength of thislight in glass is about 388.0 nm d) The critical angle for an air-water boundary is about 48.8. e) The red-light refracts through larger angles than the violet light
