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 11
A beam of white light passes through a colored filter. What happens to the transmitted light?
A student shines a laser through a block of acrylic. The light bends towards the normal. What does this indicate about the speed of light in acrylic compared to air?
Define the term 'refractive index'.
Describe what happens to a beam of light as it passes through a prism.
A ray of light passes from air (n=1.00) into glass (n=1.50) at an angle of 30° to the normal. Calculate the angle of refraction in the glass. (Use Snell's Law: n1sinθ1 = n2sinθ2)
A student observes that a pencil appears broken at the water surface in a glass. This is due to (1) Reflection, (2) Refraction, (3) Diffraction, (4) Dispersion
A student shines a flashlight through a tank of water containing milk. The beam becomes visible inside the tank. What phenomenon is responsible for this? (1) Reflection, (2) Refraction, (3) Scattering, (4) Absorption

Light travels fastest in which of the following? (1) Air, (2) Water, (3) Glass, (4) Diamond
Which color of visible light is transmitted least through a red filter? (1) Red, (2) Blue, (3) Green, (4) Yellow
A glass window appears clear because it ________ most of the visible light.
Light can be transmitted, absorbed, or ________ by a material.
The phenomenon where light changes direction as it passes from one medium to another is called ________.
The process by which light passes through a material without being scattered is called ________.
The refractive index of diamond is about 2.42. Is the speed of light in diamond higher or lower than in water?
True or False: A frosted glass window is an example of a translucent material.
True or False: All wavelengths of visible light are transmitted equally through a colored filter.
True or False: The angle of incidence is always equal to the angle of refraction.
