Reflection

1. When does reflection occur?

• When light hits an object and bounces in another direction.

• When light passes through an object without changing its direction.

• When light hits an object and it is absorbed by the object.

What happens when light bounces off a smooth reflective surface?

• All the rays reflect in one direction.

• Part of the rays reflect in one direction whereas the rest of them reflect in different directions.

• All the rays pass through that surface.

What happens when light bounces off a rough reflective surface?

• The rays reflect in many different directions.

• All the rays reflect in the same direction.

• Most of the rays pass through the surface without changing their direction.

What is the law of reflection?

• The angle of incidence is equal to the angle of reflection.

• The angle of incidence is greater than the angle of reflection.

• The angle of incidence is less than the angle of reflection.

What is the main difference between specular and diffuse reflection?

• Specular reflection occurs on smooth surfaces, while diffuse reflection occurs on rough surfaces.

• Specular reflection occurs on rough surfaces, while diffuse reflection occurs on smooth surfaces.

• Specular reflection scatters light, while diffuse reflection focuses light.

• Specular reflection absorbs light, while diffuse reflection reflects light.
