how can you prove rectilinear propagation of light
Answers
Answer:
Explanation:
Light travels in a straight line. This is called rectilinear propagation of light
Activity:
Take a straight straw and look at the light rays through it.
Take another straw which is bent and try to look at the light rays through it. You will observe that when the straw was straight you could see the light and when the straw was bent you could not see the light.
This means that we cannot bend the ray of light to travel through the bent straw.
Thus, this activity proves that light travels in a straight line.
Answer:
well through a experiment
take 2 types of tube : 1st one should be straight and hollow and now take a torch and flash the light from hollow tube and keep second end towards wall u will see light on walls
now, moving forward take 2nd tube irregular but not straight but can be hollow and now pass light through it u will not able to see it.
so simple experiment u may try at home also
