Reflection of Light Quiz

What is a plane mirror?

• A mirror that distorts the image

• A mirror that reflects light without distorting the image

• A mirror that absorbs light

• A mirror that refracts light

What does the Law of Reflection state?

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

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

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

• The angle of incidence has no relation to the angle of reflection

What is the mathematical formulation of the Law of Reflection?

• i = r

• i > r

• i < r

• i ≠ r

What happens when a light beam strikes a mirror at different angles of incidence?

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

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

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

• The angle of reflection has no relation to the angle of incidence

What should be marked on the table to set up the experiment?

• The position of the light source

• The position of the observer

• The position of the plane mirror

• The position of the normal line

How can the angle of incidence and reflection be determined?

• By measuring the distance traveled by the light

• By measuring the intensity of the reflected light

• By measuring the angle between the incoming ray and the normal

• By measuring the angle between the reflected ray and the normal

What should be checked when comparing the angles of incidence and reflection?

• If the angle of incidence is always greater than the angle of reflection

• If the angle of incidence is always less than the angle of reflection

• If the angle of incidence is always equal to the angle of reflection

• If the angle of incidence has no relation to the angle of reflection

What should be done as an extension task?

• Plot a graph of the angle of incidence against the distance traveled by the light

• Plot a graph of the angle of incidence against the intensity of the reflected light

• Plot a graph of the angle of incidence against the angle of reflection

• Plot a graph of the angle of incidence against the angle of refraction

What does a straight line graph of the angle of incidence against the angle of reflection indicate?

• There is no relationship between the angle of incidence and the angle of reflection

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

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

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

Are there any unexpected results in the data?

• No, all the results are as expected

• Yes, the angle of reflection is always greater than the angle of incidence
