Answer 1

Answer #1

Microwave oven outputs 1.5 kJ of energy per second.

Energy of one photon = hv = 6.626 * 10-34 * 2550 = 1.69 * 10-30 J

Therefore photons emitted per second by the antenna is given by,

1.5 * 103 6 = 2.242 * 1032 photons per second

i need it in c++ coding Using c ++ language The power of the microwave can be calculated as follows: Power=Work Time Work is measured in joules (I) and time is measured in seconds (s), so power is expressed in joules per second (J/s) and also known as the watt (W). For example, assume that a microwave oven does 24,000 joules of work in 30 seconds. Then the power of the microwave is 800 J/s, or 800 W. Write a...

One watt (W) is equal to 1 J/s. Assume that 5.0% of the energy output of a 75 watt light bulb is visible light and that the average wavelength of the light is 550 nm, how many photons per second are emitted by the light bulb? If 5.0% of the energy of a 75 watt light bulb is visible light, then the rate of energy of all the photons emitted is J/s (3 s.f.). A 550 nm wavelength is the...
