Waves and Oscillations

What is the period of a wave?

• The number of waves passing a point per unit time

• The distance between two consecutive points in phase

• The time taken for one complete cycle of the wave

• The maximum displacement from the mean position

Which of the following is a characteristic of a transverse wave?

• Particles of the medium move parallel to the direction of the wave

• Particles of the medium move perpendicular to the direction of the wave

• The wave requires a medium to propagate

• The wave has varying amplitude

The frequency of a simple harmonic oscillator is given by:

• f = 2 * pi * sqrt(k / m)
• f = 1 / (2 * pi) * sqrt(m / k)
• f = 1 / (2 * pi) * sqrt(m * k)
• f = 1 / (2 * pi) * sqrt(k / m)

What type of wave is a sound wave in air?

• Transverse

• Longitudinal

• Electromagnetic

• Stationary

What is the amplitude of a wave?

• The number of waves passing a point per unit time

• The distance between two consecutive points in phase

• The maximum displacement from the mean position

• The time taken for one complete cycle of the wave

Which of the following is a characteristic of a longitudinal wave?

• Particles of the medium move parallel to the direction of the wave

• Particles of the medium move perpendicular to the direction of the wave

• The wave requires a medium to propagate

• The wave has varying amplitude

What is the speed of a wave in a vacuum?

• 300,000 km/s

• 150,000 km/s

• 0 km/s

• Depends on the wavelength

What is the formula for calculating the speed of a wave in a medium?

• Speed = Frequency * Wavelength

• Speed = Amplitude * Frequency

• Speed = Wavelength / Frequency

• Speed = Frequency / Amplitude

Which of the following waves can travel through a vacuum?

• Sound waves

• Light waves

• Water waves

• Seismic waves

What is the relationship between the frequency and period of a wave?

• Frequency is the reciprocal of the period

• Frequency is equal to the period

• Frequency is the square of the period

• Frequency is the double of the period
