Microwaves are part of the electromagnetic spectrum and travel with a speed of 3.00 x 108 m/s, also known as 'c' the speed of light. Microwaves are defined to have a wavelength between 10 mm and 1 meter. What is the frequency of the microwaves produced when you heat up pizza pockets if the microwaves produced have a wavelength of 15cm. (

2. A satellite orbiting the Earth is powered by photovoltaic (“solar”) panels that convertlight energy to electricity with a conversion rate of 15.0%. Telemetry from the satelliteindicates that the panels are supplying a peak power output of 3.60 kW, and the specificationsof the panels state that they have 16 m^2 of light-collecting surface area. The radius of theSun and its distance from Earth have long been known to be 6.96 ×10^8 m and 1.50 ×10^11m, respectively. Assume the Sun radiates approximately as a blackbody and calculate thesurface temperature of the Sun.
