Rectilinear Propagation of Light starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Rectilinear Propagation of Light.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A student observes that the shadow of a tree is sharp at noon but blurred in the evening. Explain why.
A torch is shone through a straight tube. The light passes through easily. If the tube is bent, the light does not pass through. What does this demonstrate?
Describe an experiment to demonstrate the rectilinear propagation of light using three cardboards with holes.
Describe how the rectilinear propagation of light explains the occurrence of a solar eclipse.
A student observes that the shadow of a tree is sharp at noon but blurred in the evening. Explain why.
A student places a stick vertically in a tank of clear water. The stick appears bent at the surface. Does this observation support rectilinear propagation of light?
A torch is shone through a straight tube. The light passes through easily. If the tube is bent, the light does not pass through. What does this demonstrate?
A laser beam is directed through a tank filled with clear water. If a small amount of milk is added to the water, the path of the laser beam becomes visible. Explain how this observation relates to the rectilinear propagation of light.
