Phys 165 Module 6 Exam Questions
And Answers | Solved
What do we call motion that is repeated as a function of time? CORRECT ANSWERS
Periodic Motion
Of the following objects in motion, which one is exhibiting simple harmonic motion?
CORRECT ANSWERS Pendulum swinging back and forth
True or False: A scientist wants to make the period of a pendulum smaller. One way to
accomplish this would be to increase the acceleration due to gravity. CORRECT
ANSWERS True
True or False: A scientist is experimenting with an object bouncing on a spring. In order
to decrease the period of the object bouncing on the spring, the scientist could do either
of the following: increase the mass of the object or decrease the spring constant of the
spring CORRECT ANSWERS False
True or False: Electromagnetic waves need a medium to disturb.
You Answered CORRECT ANSWERS False
Which of the following is a longitudinal wave? CORRECT ANSWERS Sound
True or False: According to the Law of Reflection, the angle of incidence is the same
size as the angle of reflection. CORRECT ANSWERS True
Which of the following is the name of the property of waves when one wave occupies
the same space as another wave at the same time? CORRECT ANSWERS
Superposition
True or False: Constructive interference is the property of waves where the
superposition of two waves results in a wave that is larger than the waves that are
overlapping. CORRECT ANSWERS True
Glasses enable people to see more clearly by forcing light to move through the glass
and change directions. What property of waves do glasses use to do this? CORRECT
ANSWERS Refraction
A bob with a large mass is supported by a rope and swings back and forth while friction
acting on the system is negligible. For this pendulum, answer the following questions:
a. In which part of the swing does the pendulum bob have the most kinetic energy?
b. In which part of the swing does the pendulum bob have the most gravitational
potential energy? CORRECT ANSWERS a) In the middle of the swing or at the bottom
of the swing
