Wave Worksheet 1 Answer Key
Wave Worksheet 1 is designed to test your understanding of wave concepts, including types of waves, wave properties, and wave behavior. Below, you’ll find the answers to the worksheet, along with explanations to help you understand the material.
Section 1: Multiple Choice Questions
- What type of wave requires a physical medium to propagate?
A) Electromagnetic wave B) Mechanical wave C) Transverse wave D) Longitudinal wave
Answer: B) Mechanical wave
Explanation: Mechanical waves require a physical medium, such as water or air, to propagate. Electromagnetic waves, on the other hand, can travel through a vacuum.
- Which of the following is a characteristic of a transverse wave?
A) The wave propagates in the same direction as the particle motion. B) The wave propagates perpendicular to the direction of particle motion. C) The wave has a constant frequency. D) The wave has a constant wavelength.
Answer: B) The wave propagates perpendicular to the direction of particle motion.
Explanation: In a transverse wave, the particles move perpendicular to the direction of wave propagation.
- What is the term for the distance between two consecutive peaks or troughs of a wave?
A) Wavelength B) Frequency C) Amplitude D) Period
Answer: A) Wavelength
Explanation: The wavelength is the distance between two consecutive peaks or troughs of a wave.
Section 2: Short Answer Questions
- Describe the difference between a longitudinal wave and a transverse wave.
Answer: A longitudinal wave propagates in the same direction as the particle motion, whereas a transverse wave propagates perpendicular to the direction of particle motion.
- What is the relationship between the frequency and wavelength of a wave?
Answer: The frequency and wavelength of a wave are inversely proportional. As the frequency increases, the wavelength decreases.
Section 3: Problems
- A wave has a frequency of 50 Hz and a wavelength of 2 meters. What is the speed of the wave?
Answer: v = λf = (2 m)(50 Hz) = 100 m/s
Explanation: The speed of the wave is calculated by multiplying the wavelength and frequency.
- A wave has a speed of 300 m/s and a frequency of 100 Hz. What is the wavelength of the wave?
Answer: λ = v/f = (300 m/s)/(100 Hz) = 3 m
Explanation: The wavelength is calculated by dividing the speed by the frequency.
Important Notes:
🔍 Note: Make sure to check your units when solving wave problems. The units of wavelength are typically measured in meters (m), while the units of frequency are typically measured in hertz (Hz).
📝 Note: When solving problems, be sure to show your work and label your variables clearly. This will help you avoid mistakes and ensure that you understand the material.
