Experiment to Investigate Reflection and Refraction of Light Using a Glass Block

The video tutorial explains an experiment to study light reflection and refraction using a glass block. It covers setting up the experiment, measuring angles of incidence, reflection, and refraction, and analyzing results. The experiment demonstrates that the angle of reflection equals the angle of incidence, and the angle of refraction is smaller inside the glass. The tutorial also suggests repeating the experiment with different angles of incidence for comprehensive understanding.

What is the angle between the incident ray and the normal line called?

• Angle of refraction

• Angle of deviation

• Angle of reflection

• Angle of incidence

What is the first step in conducting the experiment with the glass block?

• Draw around the glass block on paper

• Measure the angle of refraction

• Calculate the angle of reflection

• Shine a light through the glass block

At what angle is the first incident ray set in the experiment?

• 45 degrees

• 30 degrees

• 90 degrees

• 60 degrees

What tool is used to measure the angles of reflection and refraction?

• Compass

• Protractor

• Ruler

• Calculator

What is the relationship between the angle of incidence and the angle of reflection?

• They are equal

• The angle of reflection is double

• They are unrelated

• The angle of incidence is half
