Follow the questions on the simulation: 

The numbers for the simulation are going to be just a little bit off.
For question 9 refer to the guiding questions below. 

1. Adjust the wavelength to 600 nm. Calculate the energy of this wavelength. (Ans:2.07 eV)
2. Adjust the voltage so that the amount of electrons barely reach the other side of the plate. The red dot on the graph should be at the point (0, 0). This is the stopping voltage or the Max Kinetic Energy of situation. Use this (as a positive value) to calculate the work function (the minimum amount of energy necessary to escape the electron) (Ans: 1.97)

For question 10, the work function from the previous problem stays the same (it depends on the metal used), use the new wavelength to calculate the new stopping potential and check your answer.

Activ Physics 01 Double Slit: 
Answer the following questions in a complete sentence in your notebook. Label this as a Double Slit Experiment. 
1. Describe the pattern on the screen. Describe brightness and spacing. 
2. Describe the effects of increasing slit spacing.  
3. Describe the effects of increasing wavelength. Is frequency increasing/decreasing?
4. Using the values of the program and the equation derived in class, show that the spacing is 0.77 mm for a 580 nm wavelength with a slit spacing of 3 mm. Everything needs to be converted to meters. 

5.  Fill out the chart below. Show your work, check with the simulation. 
 d L Wavelength y 
 2 mm 4 m 400 nm  ?
 ? 4m 680 nm  1.36 mm  
 2.3 mm 4 m ? 0.68 mm


Activ Physics 02 Single Slit: 

Answer the following questions in a complete sentence in your notebook. Label this as a Single Slit Experiment. 

1. Describe the pattern created by a single slit interference pattern. Include a sketch of the set up in your notes. 

2. How is a single slit pattern different from a double slit?

3. Describe the effects of Increasing the slit size. 

4. Describe the effects of increasing wavelength. 

5. Write this in your notes: 

For a single slit, the equation is the same : m(wavelength)=dsin(theta). 
The biggest difference: 
In a double slit problem the central maxima is labeled as m=0, and the next bright fringe is labeled m=1 (dark bands are multiples of m=0.5)

In a single slit the first DARK FRINGE is labeled m=1, and y is the distance from the central point to the dark fringe (also HALF the width of central max; bright spot), and d is the width of the one slit. 

Label your single slit pattern with m=1 and y
 d    wavelength L y width of max
 0.34 mm 600 nm 10 m ? ?
 ? 600 nm 10 m ? 25 mm
 0.29 mm ? 10 m ? 37.3 mm
