Have I written the correct physics pricinples? Please check????
I need to explain the physics principles of the following.. I have assumed them all but I want to check if they are correct. Are they?
Rainbows - DISPERSION, splitting of white light into colours as the suns light enters the rain droplet.
Paints - COLOUR SUBTRACTION, eg. blue pigments in paint absorb all colours of white light incident but the blue and maybe some green and violet.
Colour Television - COLOUR EXTINCTION (OR ADDING COLOURS), the colours in pixels, red, green and blue combine in different shades to produce all the colours of the visible spectrum.
Car Headlight Beams - REFLECTING PARALLEL BEAMS OF LIGHT, a light source is placed at the focal point of a parabolic mirror so they light coming off it reflects parallel to one another, thus producing a penetrating beam of light.
Refracting Telescope – REFRACTION, the use of an objective lens and an eyepiece refract and bend light to produce a magnified image.
we are not your teacher so we are not going to check them at all !!!!!!
