Displacement: - The modification in position of a body in a particular direction is called as displacement. It is a vector function and its unit in SI system is meter.
Distance: The actual length of path traversed by a body in a sub interval of time is known as distance. It is the actual path travelled by an object between its final and initial positions. It is a scalar function and its unit in SI is meter. Displacement can be positive, zero or negative but distance is always positive. If a particle goes in a straight line without modification in its direction, the value of displacement is same to the distance travelled. Otherwise it is usually less than it. Thus, Displacement distance
Does sunlight reflected off a mirror enhance the temperature of the sun-rays? A standard planar mirror will not enhance the energy contained in the rays that reflect off it. In

Magnification is the ratio of size of image to the size of object. hence it is a dimensionless constant. It has no units. 1/m is not its unit.(1/m is the unit of power=DIOPTRE)
Snell's Law: The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing from one medium to another medium. That is Sini/Sinr
