A popular kitchen appliance produces electromagnetic radiation with a frequency of 2450 MHz. With reference to Figure 6.4, answer the following: (a) Estimate the wavelength of this radiation. (b) Would the radiation produced by the appliance be visible to the human eye? (c) If the radiation is not visible, do photons of this radiation have more or less energy than photons of visible light? (d) Which of the following is the appliance likely to be? (i) A toaster oven, (ii) A microwave oven, or (iii) An electric hotplate.

b) Human eye is a detector for very narrow range of electromagnetic radiation – from 400 to 700 nm. This radiation has much longer wavelength and will not be visible by human eye.

c) Photons of tis radiation have less energy than the radiation of visible light, as wavelength is inversely proportional to the energy of radiation:

d) From Figure 6.4, we see that the wavelength of microwaves is in the range of 0.1 m. This apparatus is probably a microwave oven.
