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 12
A beam of light passes through a foggy atmosphere. The path of the beam becomes visible. What property of light does this illustrate?
A laser beam is shone through a straight tube filled with smoke. The path of the beam is visible. What does this demonstrate?
A student observes that the shadow of a tree is longer in the early morning than at noon. Explain this observation based on the rectilinear propagation of light.
A student places three cardboards with holes in a straight line and shines a torch through them. The light passes through all holes. What does this demonstrate?
Describe an experiment to demonstrate the rectilinear propagation of light using three cardboards and a candle.
Describe how the rectilinear propagation of light is used in the working of a pinhole camera.
Describe how the rectilinear propagation of light leads to the formation of a solar eclipse.
Explain why a lunar eclipse occurs only when the Sun, Earth, and Moon are in a straight line.
Explain why shadows have sharp edges when the source of light is small and at a distance.
Explain why stars cannot be seen during the day, based on the rectilinear propagation of light.
Explain why we cannot see around corners due to rectilinear propagation of light.
If a light source is placed at the center of a spherical opaque object, will a shadow be formed?
If an opaque object is placed in the path of light, what is formed on the opposite side?
State the law of rectilinear propagation of light.
