Answer 2

Answer:

Reflection, refraction and rectilinear propagation are the properties of light.

Therefore, the option (iv) is correct.

Explanation:

• When the light incident on a surface, it partly goes back which is called reflected light. The phenomenon is called reflection. he incident ray and reflected ray lie on the same plane. The angle of incidence and angle of reflection are equal.
• The light changes its path when travels from one medium to another medium. The phenomenon is called refraction. The ratio of sine of the angle of incidence to the sine angle of refraction is constant for two media.
• Until light does not suffer refraction or reflection, it travels in the straight line. When the light passes through a homogeneous medium (have one same refractive index ), it does not deviate from its path. This property of light is called rectilinear propagation.
