Question

Give tricks to remember laws of reflection and refraction

Answer 1

simple.....refraction means bending....during refraction the light bendins wwhen moving frm one media to the other...but during reflection li8 will travel only through 1 media n no bending will take place

Answer 2

It is very simple to remember both the laws.Both of them have first laws common only with the difference of reflction and refraction.

___________________________

However Second law is Different for both.

For reflection__The Angle of incidence is always equal to angle of refraction.

< i= < r

For refraction__Ratio of sine of angle of incidence to the sine of angle of refraction is constant for a given pair of media.

Sin i/ Sinr = Constant
