1-300 nm enters the glass with refractive index of ngls = 1.5. What will be the frequency of this ultra-violet light in the glass? a) 3.33 * 10^14 Hz b) 5 * 10^14 Hz c) 7.5 * 10^14 Hz d) 10 * 10^14 Hz e) 10^14 Hz 2. A yellow light with a frequency of 5.0 * 10^14 Hz and an index of refraction, Ipool = 1.33, is allowed to pass in a swimming pool. What will be the wavelength in the pool? a) 400 nm b) 451 nm c) 500 nm d) 600 nm 3. A red laser light with a wavelength of 650 nm is used to produce an interference pattern with a width of 1 mm. In later time, the laser light is replaced with a green light of 530 nm. What can we say about the width of the new interference pattern of the green laser? a) The width increases b) The width decreases c) The width stays the same d) It is inconclusive 4.

1. If q1 and q2 are opposite charges, they attract and the electric potential is a negative value, as in the case of gravitational potential energy. True or False? 2. The force vectors on a positively charged sphere are away from the sphere. True or False? 3. For a charge q1 moving in the electric field of q2 in a vacuum, the loss of electric potential energy is equal to the gain in kinetic energy. True or False? 4. Coulomb’s law is extremely accurate under the conditions that the spheres are small and that the spheres are also small compared to the distance between them. True or False? 5. A small negative charge is used to determine the direction of the electric field lines around a charge. True or False?

True or False 1- The magnetic force experienced by a charged particle moving in a magnetic field will be minimum when it moves parallel to the field. ( ) 2- A particle of mass m charge q and speed V enters a uniform magnetic B. The radius r of the circle is directly proportional to B. ( ) 3 -Current produced by moving the loop of wire across a magnetic field is called induced current. ( ) 4 -An electron enters a region where the electric field E is perpendicular to the magnetic field B. It will suffer no deflection if E = BV. ( ) 5 -When an electron moving with a uniform speed in a vacuum enters a magnetic field in a direction perpendicular to the field the subsequent path of the electron is a straight line parallel to the field. ( ) 6 -A current carrying conductor is placed in a uniform magnetic field parallel to it. The magnetic force experienced by the conductor is F= 1/ B sin. ( ) 7 -A magnetic compass will be deflected if it is kept near a charge in motion. ( ) 8 -Two parallel wires carrying currents in the opposite directions attract each other. 9 -A magnetic field exerts a force if the charged particle is moving in the direction of the magnetic field lines. ( )
