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.

A beam of light passes through three different materials: air, water, and glass. In which material does the light travel slowest?
A ray of light passes from water (refractive index = 1.33) into air (refractive index = 1.00). Does the light speed up or slow down?
A student measures the amount of light passing through two different materials. Material A transmits 90% of light, and Material B transmits 30%. Which material is more transparent?
A student observes that a glass of water appears to have a straw bent at the surface. What phenomenon is responsible for this observation?
A student shines a laser pointer through a glass of water and observes the beam bending. What property of water causes this effect?
A window is made of a special glass that only allows 60% of the incident light to pass through. What is the transmission percentage of the glass?
Describe how the thickness of a material affects the transmission of light through it.
Describe what happens to the intensity of light as it passes through a thick piece of tinted glass.
Describe what happens to the path of light when it passes from air into water at an angle.
Explain the difference between transparent, translucent, and opaque materials with examples.
Explain why a piece of black paper feels warmer in sunlight than a piece of white paper.
Explain why frosted glass is used in bathroom windows.
Explain why sunglasses are often made from tinted or polarized materials.
Explain why you cannot see through a wooden door.
If a material transmits 80% of the incident light, what percentage is either absorbed or reflected?
What is meant by the transmission of light?
