Who gave laws of reflection?

Answer 1

Specular reflection is the mirror-like reflection of light(or of other kinds of wave) from a surface, in which light from a single incoming direction (a ray) is reflected into a single outgoing direction. Such behavior is described by the law of reflection, which states that the direction of incoming light (the incident ray), and the direction of outgoing light reflected (the reflected ray) make the same angle with respect to the surface normal, thus the angle of incidence equals the angle of reflection ( in the figure), and that the incident, normal, and reflected directions are coplanar. This behavior was first discovered through careful observation and measurement by Hero of Alexandria (AD c. 10-70).

Answer 2

Galileo made the first refracting telescope used to study space in 1609. He used it to discover four of the moons orbiting Jupiter. Galileo also used his refracting telescope to map the surface of the moon. Galileo could see objects 20 times smaller than the human eye could using his telescope.

Answer 3

Reflection is a basic property of the natural universe and the laws of physics; nobody "invented" it. Probably the earliest animals noticed their reflections in a still pool of water; we can be certain that humans did. The Greek myth of Narcissus, who fell in love with his own reflection in the pond, is proof enough of that.

Understanding of the science and the math behind reflections had to wait until the Italian Renaissance, with artists and architects like like Brunelleschi, to work out how it all worked.

Answer 4

The laws of reflection were formulated by the ancient Greek mathematician and physicist, Euclid. These laws state that the angle of incidence is equal to the angle of reflection, and that the incident ray, the reflected ray, and the normal at the point of incidence all lie in the same plane.
