10 Questions
What is the aim of the experiment described?
To observe the path of light
What material is required for the experiment?
Rubber ball
What are the observations when the tube is straight?
The flame can be seen
What conclusion can be drawn from the observations?
Light travels in a straight line
What happens when the tube is bent according to the experiment?
The flame cannot be seen through the tube
Explain what happens to the visibility of the flame when looking through a straight tube compared to a bent tube.
Flame is visible when the tube is straight, but not visible when the tube is bent.
Describe the significance of the observations made regarding the path of light in the experiment.
The observations indicate that light travels in a straight line.
Explain why the flame is visible through the tube when it is straight but not visible when it is bent.
The straight tube allows light to travel in a straight line to the observer's eye, while the bent tube disrupts this path.
What would happen to the visibility of the flame if the tube was twisted instead of being bent?
The flame may still be visible when the tube is twisted, as long as the light path is not obstructed.
Discuss how the concept of light traveling in a straight line is applicable in everyday scenarios.
Examples can include shadows being cast, reflections in mirrors, and how we see objects in a direct line of sight.
Explore the path of light using a lighted candle and a hollow tube. Observe how the light behaves when the tube is straight versus when it is bent, and draw conclusions based on your observations.
