Answer 1

opaque objects do not let the light to pass through them . for example , blackboard .

Answer 2

If only blue light is shone onto a red shirt, the shirt would appear black, because the blue would be absorbed and there would be no red light to be reflected. White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.
