Photons absorbed in matter are converted to heat. A source emitting n photon/sec of frequency is used to convert 1 kg of ice at to water at . Then, the time T taken for the conversion:
a. | decreases with increasing n, with ν fixed |
b. | decreases with n fixed, ν increasing |
c. | remains constant with n and ν changing such that n ν =constant |
d. | increases when the product n ν increases |
1. (b, d)
2. (a, c, d)
3. (a, d)
4. (a, b, c)
