Base your answers to questions 1 through 4 on the information and diagram below. The diagram below is provided for practice purposes only. Be sure your final answer appears on your answer paper. A ray of monochromatic light of frequency 5.00 × 1014 hertz is incident on a mirror and reflected, as shown. | |
1.
Using a protractor and ruler, construct and label the normal to the
mirror at the point of incidence on the diagram on your answer paper.
[1] 2. Using a protractor, measure the angle of incidence to the nearest degree and record the value on your answer paper. [1] 3. Determine the wavelength of the ray of light. [Show all calculations, including the equation and substitution with units.] [2] |
|
4. What is the color of the ray of light? [1] | |
Base your answers to questions 5 through 6 on the information below. A
0.12-meter-long electromagnetic (radar) wave is emitted by a weather
station and reflected from a nearby thunderstorm.

A 20.-kg block is
placed at the top of a 10.-meter-long inclined plane. The block starts
from rest and slides without friction down the length of the incline.
7. Determine the gravitational potential energy of the block at the top of the incline. [Show all calculations, including the equation and substitution with units.] [2]
8. Determine the kinetic energy of the block just as it reaches the bottom of the incline. [1]

12. Explain what would happen if a
4.50-electronvolt photon were incident on a mercury atom in the ground
state. [1]
Base your answers to questions 13 through 15 on the information and wave diagrams below. Two waves, A and B, pass through the same medium at the same time.
13. On the grid below, sketch the wave pattern produced when the two waves interfere. The grid below is provided for practice purposes only. [3]
14. Name a wave characteristic that is the same for both wave A and wave B. [1]
|
A
mercury atom makes a direct transition from energy level e to energy level b.

Base your answers
to questions 16 and 17 on the information and diagram below which shows a
light ray in water incident at an angle of 60.o
on a boundary with plastic. 16. Using a protractor, measure the angle of refraction to the nearest degree. Record the value below.

Base your answers to questions 18 and 19 on the information below. A 5.0-kilogram block weighing 49 newtons sits on a frictionless, horizontal surface. A horizontal force of 20. newtons toward the right is applied to the block. [Neglect air resistance.] 18. On the diagram on your answer paper, draw a vector to represent each of the three forces acting on the block. Use a ruler and a scale of 1.0
centimeter = 10. newtons. Begin
each vector at point C and label its magnitude in newtons. The diagram below
is to be used for practice purposes only. Be sure your final answer appears
on your answer paper. |
