# Multiple choice questions about SHM

• phys1618
In summary, the conversation discusses reflection in relation to waves and how it applies to both transverse and longitudinal waves. It also mentions the effect of increased mass on the period of vibrations and the relationship between displacement and maximum velocity of a bob on a spring. The answers provided are correct, with light being a transverse wave and sound being a longitudinal wave.

## Homework Statement

1.Reflection goes with
a. longitudnal wave
b.trasnsverse wave
c. both
d.neither
2.
if mass of teh bob on a springs are increased, howe whould that affet the period of the vibrations?

3. if a spring is released fr. progressively larger displacments, how owould this affect eh e max. velocity of teh bob.

## The Attempt at a Solution

1. transverse, because reflection refers to light right?
2. increase becase T=2pi(sq.root(m/k))
3.increase because vmax=2pi*displacement/(T)

For the answer to number 1) What kind of wave is light? Does light reflect? What kind of wave is sound? Ever hear an echo? (Check Wikipedia if you don't know the answers to my questions)

yes it does. light is transverse and sounds is longitudinal...so i guess the answer is c. both.

Yup!

thank you.

## 1. What is SHM (Simple Harmonic Motion)?

SHM is a type of periodic motion where an object moves back and forth along a straight line, with its acceleration directly proportional to its displacement from a fixed point. This type of motion is commonly observed in systems such as springs and pendulums.

## 2. How are multiple choice questions about SHM useful?

Multiple choice questions about SHM are useful for assessing and testing a person's understanding of the concepts and principles related to SHM. They can also be used as a teaching tool to help reinforce the material and identify areas for further study.

## 3. What are some common examples of SHM?

Some common examples of SHM include a mass attached to a spring, a pendulum swinging back and forth, and a mass on a horizontal spring undergoing simple harmonic motion when acted upon by a periodic force.

## 4. How are the parameters of SHM related to each other?

The parameters of SHM, such as amplitude, frequency, and period, are all interconnected and can be calculated using each other. For example, the period is inversely proportional to the frequency, while the amplitude is directly proportional to the energy of the system.

## 5. How can understanding SHM be applied in real-life situations?

Understanding SHM can be applied in various real-life situations, such as designing and analyzing mechanical systems, predicting the behavior of waves, and understanding the motion of celestial bodies. It also has practical applications in fields such as engineering, physics, and medicine.
