What is reflection?

• Reflection is the bouncing  of light off the surface that it strikes on.

• Reflection is the bending of light off the surface that it strikes on

• Reflection is the bending of light off the surface that it strikes on.

• Reflection is the scattering of light off the surface that it strikes on.

According to the laws of reflection, if i = angle of incidence and r = angle of reflection

• i >  r

• r >  i

• i=r

• i is not equal to r

When a parallel beam of light falls on polished silver, 

• the light will be scattered

• divergent beam of light will be reflected

• parallel beam of light will be reflected

• a convergent beam of light will be reflected
