Transmission of Light
Physics ⇒ Light and Optics
Transmission of Light starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Transmission 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 8
A beam of light passes through three materials: air, water, and glass. In which material does light travel the slowest?
A student observes that a red filter only allows red light to pass through. What does this tell you about the transmission of light through colored filters?
Describe what happens to light when it strikes an opaque object.
Describe what is meant by selective transmission of light.

A material that allows some light to pass through but not all is called __________.
Fill in the blank: The __________ of a material determines how much light it transmits, reflects, or absorbs.
Fill in the blank: The process by which light passes through a material without being scattered is called __________ transmission.
If a material transmits no light, it is called __________.
True or False: All transparent materials transmit 100% of the light that hits them.
True or False: Light can be transmitted through a vacuum.
True or False: Opaque materials do not allow any light to pass through them.
True or False: The amount of light transmitted through a material depends on its thickness.
