HEY MATE!!!❤❤❤HERE'S UR ANSWER!!! ❤❤
ANS1. THE FORMATION OF RAINBOW IS DUE TO THE DISPERSION OF WHITE LIGHT.
THE PROCESS IS CALLED REFRACTION.
ANS.2-THE FORMATION OF IMAGE OF AN OBJECT BY A PLANE MIRROR IS THE PHENOMENON CALLED AS LATERAL INVERSION AND REFLECTION OF LIGHT.
SOME MORE INFORMATION:
Q. HOW IS A RAINBOW FORMED?
ANS -A rainbow is a natural spectrum of sunlight in the form of bows appearing in the sky when the sun shines on rain drops.
It is combined result of reflection, refraction and dispersion of sunlight from water droplets, in atmosphere.
Always it formed in the direction opposite to the sun.
To see a rainbow, the sun must be behind us and the water droplets falling in front of us.
When a sunlight enters into a spherical rain drop, it is refracted and dispersed. The different colours of light bent in different angles.
When different colours of light fall on the back inner surface of drop, it (water drop) reflects (different colours of light) internally (total internal reflection).
The water drops again refracts the different colours, when it comes out from the raindrop.
After leaving this different colours from the raindrop as rainbow, reach our eye. Thus, we see a rainbow.
Q. DESCRIBE THE IMAGE FORMED IN A PLANE MIRROR.
ANS-
In Plane mirrors, the image is a virtual image, and is the same distance behind the mirror as the object is in front of the mirror. The image is also the same size as the object. These images are also parity inverted, which means they have a left-right inversion.
Properties of image formed in plane mirror are same size as object, laterally inverted (left becomes right, right becomes left), upright, virtual and as far behind the mirror as the object is in front.
