What does the word " reflection " mean?
Light wave reflection occurs when electromagnetic light photons strike a medium's surface and bounce back.
Explain is it Transparent, Translucent or Opaque?
Explain how you know in 1-2 sentences.
A glass window
Transparent
All light passes through the object.
Explain the energy ( Amplitude) of different light waves. (High or Low) How do you know?
The sun
High-energy light wave. I know this because it starts in space and travels to Earth. It can cause sunburns, plants to grow etc..
Give me an example of regular reflection in real life and how you know it is reflection?
Regular Reflection happens when light hits an object and is reflected back 100%.
What did you do and learn in the Refraction Lab?
Extra points if you remember who was in your groups!
In the Refraction Lab, students explored Refraction and bending of light in different mediums, such as water and they explored different activities and were able to model and explain their observations in their groups.
What does the word Absorption mean?
Absorption means light waves are hitting a physical object and turning into heat energy.
Explain is it Transparent, Translucent or Opaque?
Explain how you know in 1-2 sentences.
A pair of dark blue sunglasses
Translucent
Some of the light goes through and it scatters
Explain the energy ( Amplitude) of different light waves. (High or Low) How do you know?
A little one-battery flashlight
Low amplitude. The power is by one little battery and the bulb is small.
Give an example of Diffused Reflection in real life and how do you know?
Diffused reflection is when light hits a bumpy surface and is not reflected back at 100%.
What did you learn in the color Vision Lab with skittles?
In the color vision lab, students explored how you can group all the different colored skittles using the primary light colors Red, Green and Blue.
What does the word Refraction mean?
The word refraction means the bending of light waves in different mediums.
Explain is it Transparent, Translucent or Opaque?
Explain how you know in 1-2 sentences.
our slate desk tops
Opaque none of the light passes through.
Explain the energy ( Amplitude) of different light waves. (High or Low) How do you know?
Bright headlights from a big Truck
High Amplitude. The beams of the headlights can travel long distances and help the driver see far in front of them.
Give an example of refraction in real life and how you know.
Refraction happens when light passes through a medium and light bends, and it magnifies different physical objects.
What did you learn and do in the Phet color Vision Lab?
(the virtual one)
In the PhET Color Vision Lab, students were asked to explore the simulation of photons and how they interact with different colored light and different colored filters, and how colored light is absorbed and what is reflected back to the eye.
What does the word Translucent mean?
Translucent means light waves can go through an object, but some get absorbed, and scattered. Examples: a stained-glass window and sunglasses.
Explain is it Transparent, Translucent or Opaque?
Explain how you know in 1-2 sentences.
A lamp shade
Translucent: some of the light shines through, and some gets absorbed and scattered.
Explain the energy ( Amplitude) of different light waves. (High or Low) How do you know?
The light on our Iphones.
Low amplitude.
The light beam can go only so far.
Give an example of 5 Translucent objects in real life
Translucent objects allow some light to pass through but is scattered.
What did you learn in the Reflection Lab?
In the reflection lab, students were asked to use a laser and a flashlight on different materials and explore regular and diffused reflection in real life.
What do the words Opaque and Transparent mean?
Opaque means no light can pass through a physical object, for example, our classroom wood door.
Transparent means all light can go through the object; for example, a clear glass window.
Explain is it Transparent, Translucent or Opaque?
Explain how you know in 1-2 sentences.
your plastic chair
Opaque none of the light goes through.
Explain the energy ( Amplitude) of different light waves. (High or Low) How do you know?
The lamps in our classroom.
Low amplitude. The bulbs are only so strong that the light stays within 3-4 ft of the lamp.
Give an example of 10 Opaque objects and how you know they are opaque.
Opaque objects do not allow any light to pass through.
What did students explore in the Absorption and Reflection Lab?
Students were asked to explore different mediums and different colors of mediums and how the light is either absorbed and turned into heat energy or the light is reflected and not mainly absorbed and turned into heat energy.
