Question

Theoretically the speed of light c through vacuum is expressed as c = 1/√(Mo), E, and μ, are
the electric permittivity and magnetic permeability of free space (vacuum). Therefore, for a
medium with dielectric constant, the speed of light (v) should be expressed as
O V = √(EoHo) / K
Ov=1/K √(EoHo)
v=1/√(K EoHo)
Ov=K/√(EoHo)

What is the energy of light having a frequency of (8.61x10^14)? Answer to 3 significant figures in scientific notation. Unit is case sensitive. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer X10 units
A 1.00-m² solar panel on a satellite that keeps the panel oriented perpendicular to radiation arriving from the Sun absorbs 1.40 kJ of energy every second. The satellite is located at 1.00 AU from the Sun. (The Earth-Sun distance is approximately 1.00 AU.) How long would it take an identical panel that is also oriented perpendicular to the incoming radiation to absorb the same amount of energy, if it were on an interplanetary exploration vehicle 2.85 AU from the Sun?

how would you solve this? Light is emitted from the light source, reflects from mirror surface X to the plane mirror, and then to the position of surface Z. By the time the light moves from the X to Z position, mirror surface X will have moved to the position of mirror surface Z. The light then continues to the observer. The distances from the light source and the observer to the rotating mirrors are negligible. The distance from the rotating mirrors to the plane mirror is 35.0 km.If the mirrors are rotating at 480 rev/s, the speed of light calculated from the given information is a 7.44 10–9 m/s b 1.34 108 m/s c 2.98 10–8 m/s d 3.36 107 m/s
