QUESTION:
Convert between energy units:
a. 534 kWh to J b. 215 kJ to Cal
c. 567 Cal to J d. 2.85 x 103 J to cal
ANSWER:Solution: According to Planck’s quantum theory of radiation, the amount of energy associated with a quantum(in case of light, the quantum of energy is often called photon) of radiation is proportional to the frequency of light, E = h ---(1), where h is a universal constant called Planck’s constant. is the frequency and E is the energy of a photon. Or, E = hc/ -------(2), where, is the wavelength of light and c is the velocity. Step1: a) Given, minimum frequency = 1.09 x 10 s 15 -1 Planck's constant, h = 6.626 x
