FAQs on 2025 Oscillations and Waves Mock Test for Exam Readiness
1. What is meant by oscillatory motion?
An oscillatory motion is a repetitive back-and-forth movement of an object about a fixed position, called the mean position. Common examples include the motion of a pendulum, a mass-spring system, and vibrating strings of musical instruments.
2. What are the essential properties of Simple Harmonic Motion (SHM)?
The essential properties of Simple Harmonic Motion (SHM) are:
- The restoring force is always directed towards the mean position.
- The magnitude of the restoring force is directly proportional to the displacement from the mean position (F = -kx).
- The motion is periodic and sinusoidal in nature.
3. Differentiate between periodic and non-periodic motion.
In periodic motion, the object repeats its path at regular intervals of time, such as a pendulum or planets orbiting the Sun. Non-periodic motion does not repeat in a definite time interval, such as the motion of a car on a crowded street.
4. What is the time period and frequency of an oscillating body?
The time period (T) is the time taken to complete one oscillation. The frequency (f) is the number of oscillations per second. They are related by the formula f = 1/T. Both are key parameters in describing oscillatory motion.
5. State the principle of superposition of waves.
According to the principle of superposition, when two or more waves meet at a point, the resultant displacement at that point is equal to the algebraic sum of the displacements due to individual waves. This concept explains phenomena like interference and beats.
6. What are free and forced oscillations?
Free oscillations occur when a system oscillates at its natural frequency without any external periodic force, like a struck tuning fork. Forced oscillations happen when a periodic external force drives the system, such as a swing pushed repeatedly at a fixed rate.
7. What is resonance? Give an example.
Resonance occurs when the frequency of an externally applied force matches the natural frequency of a system, leading to a significant increase in amplitude. A common example is a glass shattering when exposed to a sound at its natural frequency.
8. Define amplitude, wavelength, and phase in the context of waves.
- Amplitude: The maximum displacement from the mean position in a wave.
- Wavelength: The distance between any two consecutive points in phase, such as crest to crest or trough to trough.
- Phase: Defines the state of motion at a given point in time in the cycle of a wave and is measured in degrees or radians.
9. What is meant by a damped oscillation?
A damped oscillation is an oscillation in which the amplitude decreases gradually due to the continuous loss of energy, primarily because of friction or resistance. Over time, the motion dies out unless energy is supplied to sustain it.
10. Explain the terms reflection and refraction of waves.
- Reflection of waves occurs when a wave encounters a boundary and bounces back into the original medium.
- Refraction of waves takes place when a wave passes from one medium to another, resulting in a change in its speed and direction due to the difference in densities of the two media.
11. What are standing waves and how are they formed?
Standing waves are formed when two waves of the same frequency and amplitude traveling in opposite directions superpose in a medium, creating nodes (points of zero amplitude) and antinodes (points of maximum amplitude). This is seen in vibrating guitar strings or air columns in pipes.
12. How does a simple pendulum demonstrate oscillatory motion?
A simple pendulum demonstrates oscillatory motion as it swings back and forth about its mean position under the influence of gravity. The restoring force always acts towards the equilibrium position, and the motion repeats itself at regular time intervals, characteristic of periodic motion.
