Marked the location of the incident and emergent ray. Any student needing additional assistance should be paired with a student who has a firm understanding of the prior knowledge. . Middle I placed the paper and the flexi glass on the center of lab bench so that the ray box or the glass would not fall during the entire investigation. Analysis : Angle of Incidence ° from nearest normal Angle of Refraction ° from nearest normal Sine of Angle of Incidence ° from nearest normal Sine of Angle of Refraction ° from nearest normal 0 0 0 0 15 10 0.

They will also receive feedback during the explain discussion portion. Does this match your prediction? The teacher will pose probing questions to get an understanding of how much each pair grasps the idea of refraction: What do you see? I wonder what would happen if you put more water in the cup? Not moving the lens, we rotated the platform 10. The teacher will ask the students to discuss their answers to the questions on the worksheet. Explain that media refers to more than one medium. How much water did you need for the whole penny to be visible? In part one and part two, we believed that there was no refraction as the ray left the curved side of the lens because it entered and left through the flat side, which made the photons not get disrupted or curved.

Start with the material that bends the least and finish with the one that bends the most. The lesson begins with an engage demo placing a pencil in a glass of water. We believed that this was because the energy from the refracted ray was transferred to the reflected ray. The incident ray will split into two rays, the reflection ray and refraction ray. This is the last chance to address any misconceptions before the summative assessment. The feedback during the explain discussion portion will be less formal.

We noted that when the refracted ray began to disappear, the reflected ray began to become brighter. For the largest angles you might need to place your pin closer to the tank. This is the last chance to address any misconceptions before the summative assessment. Remember, the refracted angle is the one that goes from Water into Air and the reflected angle is the one that stays in the water. The students will be able to distinguish between reflection, refraction, and absorption, and be able to apply the information they learned about refraction to a real life situation.

In refraction, the frequency color of light changes. Some things that might account for these differences would be human error in reading the degree measurement, or failure to properly align the lens straightly on the compound line. Sorry, but copying text is forbidden on this website! Since water is denser than air, when the light passed through the water it bent allowing you to see the penny at the bottom of the cup. We observed what happened to the ray as it emergeed from the flat side of the lens and went into the air. The students place a penny on the bottom of an opaque cup then step back until they cannot see the penny.

Some districts do not allow school computers to access the site. There is a short quiz for the summative assessment. How much water did you need to see the penny? You would have to aim in front of the fish to actually hit it. They are located on opposite sides of the boundary line. We spent a minute adjusting the lens until we were satisfied and had it in the right position.

The bending of light rays is called refraction. The expected results that would need to occur to prove the validity of the Law of Reflection would be that when we conduct the experiment, the measure of the angle of incidence would have to be equal to the measurement of the angle of reflection, because this is what the Law of Reflection states. The teacher then explains what refraction is and why it happens. David Urlanda Physics Lab Report Refraction of Light — Air into Glass Purpose: When light travels through different mediums, it is being refracted. Why do you think this is happening? We can see in my data that this law is true. Don't resume your program but just record the new angle of the refracted light.

Angle of Incidence o Angle of Refraction o Sin Ф i Sin Ф R Sin Ф i Sin Ф R 0. Not moving the lens, we rotated the platform so the incident ray came in at 10. The critical angle refers to an angle of incidence that produces a corresponding emerging ray that has an angle of refraction of 90°. In this activity, it was estimated to be 43°. Prior Knowledge: The students will use what they previously learned on this standard to understand the new content on refraction.

How much water did you need to see the penny? Reflection is defined as the reversal in direction of a particle stream or wave upon encountering a boundary. The teacher will provide more formal written feedback when they answer the written elaborate question. Make enough rows for 8 different incident angles. The feedback during the explain discussion portion will be less formal. The first will be the incident angle, the second will be the reflected angle and the third will be the refracted angle. If I use this value I would actually get a closer value.
