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 9
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?

Light travels fastest in which of the following? (1) Air (2) Water (3) Glass (4) Diamond
Which of the following best describes the transmission of light through air? (1) No light passes through (2) Most light passes through (3) All light is absorbed (4) Light is scattered in all directions
Which of the following best describes the transmission of light through frosted glass? (1) All light passes straight through (2) No light passes through (3) Some light passes through but is scattered (4) Light is absorbed completely
Fill in the blank: A material that allows light to pass through it without scattering is called __________.
Fill in the blank: Materials that do not allow any light to pass through are called __________.
Fill in the blank: The __________ of a material determines how much light it transmits, absorbs, or reflects.
Fill in the blank: The __________ of a material is a measure of how much it slows down light passing through it.
True or False: All transparent materials transmit 100% of the light that strikes them.
True or False: Opaque objects do not transmit any light.
True or False: The color of a material can affect how much light it transmits.
True or False: The speed of light is the same in all materials.
