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)
