The light bending /refracting as it enters the prism it allows it to go onto an angle so that light can be visible to us
HOW ARE INFRARED RADIATION USED IN TELEVISION REMOTES?
Infrared light is used to send the signals from the television remote to the television. Infrared light is also known as just plain heat. Binary codes are what process the instructions that you command the remote to do by simply clicking a button. So the whole process of commanding a television remote to do what you need is when you click a button the binary codes are sent and then decoded along with the signals from the infrared light (heat) and your command has been performed.
EXPLAIN WHAT THE PURPOSE IS OF RADIATION THERAPY AS A TREATMENT FOR CANCER, AND IDENTIFY WHAT TYPE OF WAVE FROM THE ELECTROMAGNETIC SPECTRUM IS USED IN THERAPY.
Radiation therapy is used commonly for killing cancer cells. The way radiation therapy works is the electrically charged particles that are sent via waves from the linear accelerator (machine used to send off radiation into the body)
-INVESTIGATION QUESTION 3: USING THE PRINCIPAL OF REFRACTION, EXPLAIN WHY A SWIMMERS LEG LOOKS DIFFERENT UNDERWATER COMPARED TO OUT OF THE WATER?
Swimmers legs look different underwater because the energy that comes from the sun is transmitted though light waves, the light hits against the water causing it to refract causing an illusion. The reason the swimmers legs look different is the light bends when it hits the normal (also water in this case) so our eyes adjust to another area where the swimmers legs aren't really there
-INVESTIGATION QUESTION 4: HOW WAS THE BIONIC EYE DEVELOPED? INCLUDE INFORMATION ON HOW IT WORKS, WHAT IS MACULAR DEGENERATION, AND WHICH PATIENTS DOES IT BENEFIT?
The bionic eye is what is used to be able to allow a blind man to see. A camera which is attached to the pair of glasses transmits signals via radio waves. These radio waves are high frequency after the signal is then processed it allows the optic nerve to respond and allow the blind person to see.

NAME: Anna Girgis
PARTNER: Rhiannon Gurkin
AIM: To investigate how light rays reflect and refract. Using different lenses and mirrors.
HYPOTHESIS: The hypothesis is that light rays will shine in different directions with different mirrors and lenses causing the light to reflect and refract differently
METHOD:
SET UP OF LIGHT BOX KIT:
1) Connect your light box to your battery pack as shown by your teacher
2) Place the black plastic light distributor down with the single open shaft facing downwards.
3) Place a sheet of white paper down in front of the light box.
4) Choose a coloured square of your choice.
5) Close the sides of the box making sure no lights escape.
EXPERIMENT 1:
6) Place a concave mirror in front of the light box and fill in the table below
7) Flip over the concave mirror so it faces backwards and fill in the table
8) Place down the plane mirror so that is faces the light box and fill in the table
EXPERIMENT 2:
9) Place the concave lens in front of the light box (on the horizontal) and fill in the table below
10) Place the convex lens in front of the light box (on the horizontal) and fill in the table
11) Place the rectangular plane in front of the light box (on the diagonal) and fill in the table
12) Place the prism in front of the light box and fill in the table
EXPERIMENT 3:
13) Start with a convex lens and hold it close to your eye. Slowly move the lens away from your face until your arm is completed outstretched. Record what you see in the space below.
The convex lens makes everything look upside down and the concave lens keeps everything the same.
RESULTS
EXPERIMENT 1:
EXPERIMENT 2:
DISCUSSION:
QUESTION 1: DESCRIBE THE DIFFERENCE BETWEEN REFLECTION AND REFRACTION BASED ON WHAT YOU SAW IN YOUR RESULTS.
The difference is that reflection stays straight but reflects back and refracting bends light source away from the normal
QUESTION 2: DESCRIBE THE EFFECT OF CONCAVE AND CONVEX LENSES HAVE ON THE LIGHT THAT PASSES THROUGH THEM.
The effect convex has on the light that passes through it is the light source causes it to come together and concave spreads all the light rays out
QUESTION 3: DOES THE DISTANCE FROM THE OBJECT ALTER THE WAY THE LIGHT BENDS? EXPLAIN YOUR RESPONSE.
Yes, because if they object is further away you see that the light begins to fade and does not show a vibrant light
QUESTION 4: THE FOLLOWING IMAGE DEMONSTRATES WHAT FEATURE OF LIGHT WAVES AND WHY?
This image is reflective because the light source bends off and away off the surface
CONCLUSION:
In conclusion the students achieved that aim of investigating the different way you can reflect and refract using the different objects given. The students were also able to identify what type of light wave from the light source was or became.
