Light Travels
Travels in straight lines.
What is light?
This word describes a material that allows some light to pass through
What is translucent?
Of these three materials—clear glass, wax paper, and cardboard—this one is transparent.
What is clear glass?
True
Which would transmit more visible light: Sprite or Coca-Cola?”
What is Sprite?
This represents an arrow in our workbooks
What is the path of light?
Wax paper and frosted glass are examples of translucent T or F
True?
When light hits a transparent material, most of the light does this instead of being absorbed or reflected.
What is transmitted / passes through?
A flashlight shines on a wooden door, but no light is detected directly behind the door. What property of the door explains this observation?
What is the door is opaque and does not transmit light?
Light passes through a dirty window.
What is Transmit?
What is reflection?
This term describes light passing through a translucent material and spreading in different directions.
What is scattering?
A student shines a flashlight through clear glass and notices a bright spot on the wall behind it. What does this evidence tell you about how the glass interacts with light?
What is the glass transmits most of the light because it is transparent?
A student shines the same flashlight on clear glass and then on a thick piece of cardboard. Explain why a shadow forms behind the cardboard but much less of a shadow forms behind the glass.
What is the cardboard is opaque and blocks light from being transmitted, while the transparent glass transmits most of the light?
Light hits aluminum foil
What is Reflect?
Light travels through an object and also bounces off an object is also called these two terms
What is transmit and reflect
This animal is translucent.
What is a jellyfish?
Two materials look similar, but you can see an object clearly through Material A and only see a blurry shape through Material B. How would you classify each material?
What is Material A is transparent and Material B is translucent?
Two opaque objects are placed in sunlight: one reflects most of the incoming light, while the other absorbs most of it. Predict which object will likely become warmer and explain why.
What is the object that absorbs more light will become warmer because more of the light energy is absorbed and converted to thermal energy?
Light passes through clear plastic.
Transmit
Artificial light and Natural light travel at different speeds T or F
False?
A flashlight shines through two identical sheets. When the second one is added, the object becomes dimmer and blurrier. Explain using absorption and scattering.
Some light is absorbed by the sheet and some light is scattered in different directions.
A student can clearly see a pencil through a sheet of clear plastic. Explain what happens to the light that allows the student to see the pencil.
What is light from the pencil is transmitted through the transparent plastic and enters the student's eyes?
A black metal sheet and a white metal sheet are both opaque and placed under the same bright light. Neither transmits light, but the black sheet becomes much warmer. If both materials are opaque, why does one become hotter than the other?
What is the black sheet absorbs more of the incoming light energy, while the white sheet reflects more of it?
A window lets you see outside, but you can also see your reflection in it.
