Light Travel and Experiment Procedures

The video tutorial demonstrates an experiment to verify the rectilinear propagation of light, showing that light travels in a straight line. It begins with an introduction and aim, followed by a list of required apparatus, including three cardboard pieces and a candle. The procedure involves aligning the cardboards with holes in a straight line in front of the candle. Observations reveal that the candle flame is visible only when the cardboards are aligned, confirming the conclusion that light travels in a straight line.

What is the primary aim of the experiment discussed in the video?

• To study the reflection of light

• To measure the speed of light

• To verify that light travels in a straight line

• To understand the dispersion of light

Which of the following is NOT listed as part of the apparatus for the experiment?

• Three cardboard pieces

• A meter scale

• A mirror

• A candle

What is the first step in the procedure of the experiment?

• Observe the flame from the opposite side

• Arrange the cardboards in front of the candle

• Light the candle

• Make holes in the three cardboards

What happens when one of the cardboard pieces is moved slightly from its position?

• The flame of the candle is not visible

• The flame of the candle becomes brighter

• The flame of the candle changes color

• The flame of the candle appears larger

What conclusion is drawn from the experiment?

• Light can bend around corners

• Light changes direction when it hits a cardboard

• Light travels in a straight line

• Light is absorbed by cardboard
