Reflection of Light

What are the missing components, A and B in the illustration that shows the law of reflection?

• 2. A - Angle of reflection

     B - incident angle

  
  

• 1. A - Incident Angle

     B - Angle of Reflection

• 1. A - Incident Ray

     B - Angle of Reflection

• 1. A - Reflected Ray

     B - Angle of Reflection

Based on the illustration, if the incident ray is reflected, what will the angle of reflection be?

• 1. 45 degrees

• 1. 135 degrees

• 1. 315 degrees

• 1. 25 degrees

What is the relationship between the incident ray, reflected ray, and the normal line at the point of incidence?

• 1. They form a triangle.

• 1. They all lie in the same plane.

• 1. They are always perpendicular to each other.

• 1. They do not interact with each other.

In the context of the law of reflection, what does the normal line represent?

• 1. A line that bisects the angle of incidence and reflection.

• 1. A line that indicates the direction of the reflected ray.

• 1. A line parallel to the incident ray.

• 1. A line perpendicular to the surface at the point of incidence.

If the angle of incidence is increased, what happens to the angle of reflection according to the law of reflection?

• 1. It becomes zero.

• 1. It remains the same.

• 1. It decreases.

• 1. It increases.

What is the significance of the law of reflection in optical devices?

• 1. It only applies to mirrors.

• 1. It helps in designing lenses.

• 1. It determines the color of light reflected.

• 1. It is irrelevant to optical devices.
