Wave and Ossilation

What are the two main types of waves?

• Longitudinal waves and transverse waves

• Sound waves and light waves

• The two main types of waves are mechanical waves and electromagnetic waves.

• Radio waves and gamma rays

Explain the difference between frequency and amplitude in a wave.

• Frequency is the maximum displacement from the equilibrium position, while amplitude is the number of cycles per unit time.

• Frequency is the wavelength of the wave, while amplitude is the speed of the wave.

• Frequency is the number of cycles per unit time, while amplitude is the maximum displacement from the equilibrium position.

• Frequency is the energy carried by the wave, while amplitude is the distance between two wave crests.

Name three wave properties.

• Phase

• Velocity

• Amplitude, Frequency, Wavelength

• Energy

Define simple harmonic motion.

• Simple harmonic motion is a type of motion where the force is directly proportional to the velocity.

• Simple harmonic motion is a type of motion where the displacement is always in the same direction as the restoring force.

• Simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement from equilibrium position and acts in the opposite direction of the displacement.

• Simple harmonic motion is a type of chaotic movement with no defined pattern.

What is the equation for the speed of a wave?

• v = f - λ

• v = f / λ

• v = f * λ

• v = f + λ

Describe the relationship between wavelength and frequency of a wave.

• The relationship between wavelength and frequency of a wave is direct.

• Wavelength and frequency of a wave are unrelated.

• Wavelength and frequency of a wave are always equal.

• The relationship between wavelength and frequency of a wave is inverse.

How does the amplitude of a wave affect its energy?

• Lower amplitude waves carry more energy compared to higher amplitude waves.

• Higher amplitude waves carry less energy compared to lower amplitude waves.

• Higher amplitude waves carry more energy compared to lower amplitude waves.

• Amplitude has no effect on the energy of a wave.

What is the formula for calculating the period of a wave?

• T = f - 1

• T = f * 1

• T = 1 / f

• T = f / 1

Explain the concept of wave interference.

• Wave interference is the phenomenon where two or more waves superpose to form a resultant wave of greater, lower, or the same amplitude.

• Wave interference always results in a wave with the same amplitude as the original waves.

• Wave interference is the result of two waves canceling each other out completely.

• Wave interference only occurs in mechanical waves, not electromagnetic waves.

How does the medium through which a wave travels affect its speed?

• The speed of the wave is only affected by the color of the medium

• The medium has no impact on the speed of the wave

• Waves travel faster in mediums with higher temperatures

• Different mediums have different densities and elastic properties, affecting the speed of the wave.
