Question

black is a colour, white is a colour but black and white TV is not a coloured TV why???​

Answer 1

Answer:

Black is a colour and white is also a colour but black and white television is not colour TV. why?

Explanation:

Black is not a colour by the terms of physics we determine that black is actually absence of colour and it doesn't reflect any colour wavelength to our eyes. And white is also not a proper colour because it is mixture of all colours and isn't present independently in the light spectrum. That's why the black and white TVs are determined as colourless .
