CP Physics Numbered Heads Review covering Refraction and Lenses Test

Numbered Heads Instructions

1. Form into the designated groups

2. Take out one full sheet of paper per group and list the name of the group at the top. Then list the names of the group members and place numbers next to each name (1, 2, 3…..If four members then write 4 also). It doesn’t matter who gets what number.

3. Hand the paper to the instructor. It will be used for assessment and graded.

4. Begin reviewing/ learning the listed concepts. Make up sample questions related to the concept. Try to imagine what question the teacher will ask. Time is limited; so don’t waste it!

5. Once you understand the concepts yourself locate the group members who do not understand  by assessing them. Do not ask yes or no assessment questions.

Good Assessment. “Sam, could you show me how to do number three on the list?”

Poor Assessment. “Do you guys all know it?”

Now teach them how to answer the questions you have formulated.  

6. When the instructor calls a number randomly (ex. = 3) the three will go to a designated area alone and respond to a similar question. Make sure they have something to write with and a calculator. After they leave begin studying the next set of concepts for the next round.

7. After a short amount of time the person will then return to the group and their answer will be graded by the teacher and given to the entire group as a communal score.

8. The returning group member may be called again so they should receive extra instruction to help get caught up.

9. The scores are added at the end to determine winners. The top three groups receive extra points on the test.

Review Concepts

1.  Be able to calculate the index of refraction  of an unknown substance  given the speed of light in the substance and in a vacuum. 

2.  Find the Angle of Refraction between two media given both refractive indexes and an  angle from horizontal on the incident side.

3.  Use your knowledge of refraction and critical angle to describe what you would see if you where underwater, on the bottom, looking up towards the surface in clear water .  

4.   Find the Angle of Refraction between two media given both refractive indexes and an ingle from normal  on the 4ncident side.

5.  Solve for the index of refraction from air to of an unknown  substance given theta i and theta r  . 

 
6.  Know the cause of near and farsightedness in the eye and how to correct either with lenses.

7.  Brainstorm a product that would use refraction to accomplish a useful task  and how you would market the product.   

8.  Be able to describe the two types of images formed by converging lenses  (three words for each)

9.  Be able to describe the one kind of image formed by diverging lenses (three words)

10.  Calculate the object distance, and magnification  given focal length and image distance for a converging lens.

11.  Be able to draw #8 to scale given object height.

12.  Calculate image distance for a diverging lens given f and object distance.  Understand that f is negative.

13.  Draw the image for a diverging lens to scale.

14.  Find the critical angle given two indexes of refraction

15.  Know where to aim to spear a fish when standing on the shore, and be able to explain your answer.

Ap Physics study guide for Quantum and Nuclear Test

Here is the list of topics for the test


1.  Given an photon of  a certain frequency and knowing the stopping potential, solve for the Ke max of the ejected photoelectrons.

Understand how to express in eV units as well as in Joules.   ( to express in joules multiply volts by charge per electron)

2. Apply conservation of momentum to photons striking electrons.  Be able to explain what happens to the wavelength of a photon after it strikes an electron.

3.  Calculate wavelength or frequency of light emitted associated with the movement of the electron from a high to low quantum number.

4.  Calculate  work function given cutoff frequency  for a photon

5.  Balance a nuclear equation by understanding total reactant protons and neutrons is conserved.

6.  Select the higher energy photon based on two wavelengths

7.Calculate de Broglie wavelength from an electron's Kinetic Energy in eV.  or in Joules

8.  Find the isotopes of an element given the atomic number and the number of neutrons in the isotope

9.  Find binding energy of a particle given mass of the bound together particle using the constituent components.
