11) A glass plate has a thickness of 4.0 mm. A light beam is incident from air towards the glass plate at an angle of incidence of 60 °. How long does it take for the light beam to pass the glass plate? The refractive index of the glass is 1.55.

The extremely high temperatures needed to trigger nuclear fusion are proposed to be generated by laser irradiating a spherical pellet of deuterium and tritium fuel of diameter 1.8 mm. (a) determine the maximum fuel temperature that can be achieved by irradiating the pellet with 200 lasers, each producing a power of 550 w. the pellet has an absorptivity 0.3 and emissivity 0.8.
