Answer #1

Visible light is the part of electromagnetic sprectrum to which our eyes are sensitive. It account from 400nm to 700 nm wavelength and accounts for all colours. Any wavelength beyond the visible spectrum can not be seen by us as our eyes are not sensitive to them. Thus, the infrared can not have any colour since colour is only the property of visible sprectrum.

So, if we have two radiation, and we know that one of them is in the visible region while the other one in infrared region, then the two can be differentiated on the basis of colour as the radiation in visible spectrum would have a particular colour while the other would be colourless(not visible by eyes).

So the statement is true.

True or false? Monopolists differ from perfect competitors because monopolists make a profit. Why? a/ False. Monopolists earn economic profits in the short run and perfect competitors earn losses in the short run. The distinguishing feature is that a monopolist restricts output to increase price, whereas a perfectly competitive firm cannot influence the price. b/ False. Monopolists, like perfect competitors, may or may not earn economic profits in the short run. The distinguishing factor is that perfect competitors produce where...
