Wave speed refers to how fast a wave propagates through a medium. It is usually measured in meters per second (m/s). The wave speed depends on the properties of the medium through which the wave travels and is crucial in understanding how waves behave. Key formula: \[ v = f \times \lambda \] - v = wave speed (m/s) - f = frequency (Hz) - λ = wavelength (meters) What is Frequency? Frequency indicates how many wave cycles pass a fixed point per second. It is measured in hertz (Hz). A higher frequency means more cycles per second, which often correlates with higher energy. What is Wavelength? Wavelength is the distance between two successive points on a wave (for example, crest to crest or trough to trough). It is measured in meters or centimeters. --- Key Concepts Covered in Worksheet 1 Answer Key 1. Calculating Wave Speed Students learn to determine wave speed when given frequency and wavelength: Sample problem: - If a wave has a frequency of 50 Hz and a wavelength of 4 meters, what is its speed? Solution: \[ v = f \times \lambda = 50 \times 4 = 200\, \text{m/s} \] Answer: - Wave speed = 200 meters per second 2 2. Calculating Frequency Given wave speed and wavelength, students can find the frequency: Sample problem: - A wave travels at 300 m/s with a wavelength of 3 meters. Find its frequency. Solution: \[ f = \frac{v}{\lambda} = \frac{300}{3} = 100\, \text{Hz} \] Answer: - Frequency = 100 Hz 3. Calculating Wavelength When wave speed and frequency are known, wavelength can be calculated: Sample problem: - If a wave travels at 150 m/s and has a frequency of 30 Hz, what is its wavelength? Solution: \[ \lambda = \frac{v}{f} = \frac{150}{30} = 5\, \text{meters} \] Answer: - Wavelength = 5 meters --- Step-by-Step Solutions from Worksheet 1 Answer Key Sample Problem 1: Find the wave speed - Given: Frequency = 60 Hz, Wavelength = 2 meters - Solution: \[ v = 60 \times 2 = 120\, \text{m/s} \] - Answer: Wave speed = 120 m/s Sample Problem 2: Find the frequency - Given: Wave speed = 330 m/s, Wavelength = 11 meters - Solution: \[ f = \frac{330}{11} = 30\, \text{Hz} \] - Answer: Frequency = 30 Hz Sample Problem 3: Find the wavelength - Given: Wave speed = 340 m/s, Frequency = 85 Hz - Solution: \[ \lambda = \frac{340}{85} = 4\, \text{meters} \] - Answer: Wavelength = 4 meters --- Common Questions and Clarifications in the Answer Key Q1: Why is the wave speed important? Understanding wave speed helps in predicting how quickly signals or energy will travel through a medium, which is essential in fields like telecommunications, acoustics, and optics.
