Question 1: Define a Transverse wave and describe how it moves particles in the medium.

Answer: A Transverse wave is a wave in which particles oscillate perpendicular to the direction of wave propagation. In such waves, particles move up and down or side to side as the wave passes through.

Question 2: Explain the main difference between Transverse and Longitudinal waves.

Answer: In Transverse waves, particles oscillate perpendicular to the wave direction, while in Longitudinal waves, particles oscillate parallel to the wave direction.

Question 3: List two examples of Transverse waves and two examples of Longitudinal waves found in everyday life.

Answer: Transverse waves: waves on a string, water waves. Longitudinal waves: sound waves in air, seismic P-waves.

Question 1: A wave travels along a string with a speed of 12 meters per second and has a wavelength of 3 meters. Calculate its frequency.

Answer: Frequency = Speed / Wavelength = 12 m/s ÷ 3 m = 4 Hz

Question 2: A Longitudinal wave has a frequency of 5 Hz and a wavelength of 2 meters. What is its wave speed?

Answer: Wave speed = Frequency × Wavelength = 5 Hz × 2 m = 10 meters per second

Question 1: Describe a simple experiment to demonstrate the difference between Transverse and Longitudinal waves.

Answer: One experiment involves a rope and a slinky. For Transverse waves, shake the rope up and down; for Longitudinal waves, compress and stretch the slinky along its length. Observing the motion of particles shows the difference.

Question 2: Identify two variables that can be changed in wave experiments and mention safety precautions to consider.

Answer: Variables: amplitude and frequency. Safety precautions include avoiding excessive tension in ropes and ensuring equipment is secure to prevent injuries.

Question 1: A series of measurements shows a wave with a speed of 15 m/s, a wavelength of 5 meters, and a frequency of 3 Hz. Do these values align with the wave speed formula? Explain.

Answer: Yes. Using the formula Speed = Wavelength × Frequency, 5 m × 3 Hz = 15 m/s, which matches the given wave speed.

Question 2: A wave in a medium causes particles to oscillate in a direction parallel to wave travel. What type of wave is this, and what evidence supports your answer?

Answer: It is a Longitudinal wave. Evidence is that particles oscillate along the same direction as the wave propagates.

Question 1: Compare and contrast Transverse and Longitudinal waves, including their particle motion, examples, and how they transfer energy.

Answer: Transverse waves have particles oscillating perpendicular to wave direction, such as water waves and waves on a string. Longitudinal waves have particles oscillating parallel to wave direction, like sound waves. Both transfer energy, but their particle motion and examples differ significantly.

Question 1: Explain how understanding Longitudinal waves is important in the technology of ultrasound imaging.

Answer: Ultrasound imaging uses high-frequency Longitudinal waves that travel through body tissues. Understanding wave properties allows for accurate imaging and diagnosis without invasive procedures.

Question 2: Describe a common day-to-day scenario where Transverse waves are utilized and explain their significance.

Answer: Wireless communication signals use Transverse electromagnetic waves to transmit data. Their significance lies in enabling modern communication devices like cell phones and Wi-Fi.
