Answer:
a) a image which can be caught on screen
b) spectrum is a band of light rays with different wavelengths
c)lateral inversion is image appearing left to right
Explanation:
A real image :
A real image is the collection of focus points actually made by converging rays, while a virtual image is the collection of focus points made by extensions of diverging rays. ... A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge.
Spectrum:
a band of colours, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wave length.
Lateral Inversion:
The phenomenon where your left appears as the right and vice versa in a mirror is referred to as Lateral Inversion. A very similar thing happens if you write a word say 'MIRROR' on a piece of paper and keep in front of the mirror.
