Write down two laws of reflection ? 5. Define Pinhole camera ,?Write down two advantages of pinhole camera? 6. Define term diffused and irregular reflection? And how virtual image formed? .​

Answer 1

Answer:the motion around a circular path is called as cicular motion.

the in uniform movement is called oscillatory motion.

Explanation:

Answer 2

Explanation:

1) circular motion:circular motion is the movement along with the circumference of the circle

*an artificial satellite orbiting the earth at constant height, a stone which is tied to a rope and is beings swung in circles

oscillatory motion: oscillatory motion can be termed as repeated motion which objects repeat at the same movement

*the turning fork, the stretched string the movement of atoms in molucules
