Rectilinear Propagation of Light
Physics ⇒ Light and Optics
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 11
A light source, an opaque object, and a screen are arranged in a straight line. What will be observed on the screen?
A small opaque object is placed in the path of a narrow beam of light. What will be observed on a screen placed behind the object?
A student observes that the shadow of a tree is sharp at noon but blurred in the evening. Explain why.
Describe an experiment to demonstrate the rectilinear propagation of light using three cardboards with holes.

Fill in the blank: The formation of a sharp shadow is possible only if light travels in a ________ line.
Fill in the blank: The phenomenon of ________ is explained by the rectilinear propagation of light, where the Moon blocks sunlight from reaching the Earth.
Fill in the blank: The region of partial shadow formed when only a part of the light is blocked is called the ________.
Fill in the blank: The region of total darkness behind an opaque object is called the ________.
True or False: Light can bend around obstacles in a homogeneous medium due to rectilinear propagation.
True or False: The formation of a lunar eclipse is a result of the rectilinear propagation of light.
True or False: The rectilinear propagation of light can be observed using a laser pointer in a dusty room.
True or False: The rectilinear propagation of light explains why we see sharp edges in shadows.
