Wave Basics

2 Types of Waves Using the infograph above fill in the following blanks using the word bank provided. There are two main types of waves. The type that requires a medium to pass through is called a Mechanical Wave. There are two types of mechanical waves. One of these includes sound waves and are known as Longitudinal waves. The other type of Mechanical wave that includes water waves is known as Transverse waves.The type of wave that does not require a medium to travel through is called an Electromagnetic Wave. Examples of Electromagnetic waves includes light, Microwave, infrared, x-rays, ultraviolet, and Radio waves. Basic PartsTransverse Wave Longitudinal Wave In your science binder... Using the images above.....1. Draw and label the Transverse wave. ( Make sure to include: amplitude, crest, trough, and rest position)2. Draw and label the Longitudinal wave (Make sure to include: wavelength, compression, and rarefaction) Bozeman video Click here to watch the video. Be sure to answer the questions below. Wavelength is the distance between one point on a wave (such as the crest or trough to the same point (i.e. crest or trough) on the following wave. In a transverse wave the oscillations are Perpendicular to the movement of the wave. The symbol used to represent wavelength is called lambda (λ) and is measured in the units: meters. One important thing to remember is that waves only transfer energy from place to place NOT matter. The Amplitude of a wave is measured from the equilibrium point to either the crest or the trough. Frequency is the number of complete waves to pass a fixed point in a second and is measures in Herts (Hz). We can calculate the speed of a wave using the equation V=fλ which stands for Speed = frequencyXWavelength. In your science binder... In your Science binder turn to the same page you have the Transverse and Longitudinal waves drawn.Draw and label an example of "Wavelength- (λ)" on the Transverse wave. Apply what you know Using the image above fill in the blanks with the correct information. Make sure you include the digits AND units exactly how they appear on the chart for each. ONLY include digits for speed. NO SPACE IN BETWEEN OR IT WILL COUNT YOU INCORRECT! Transverse is the type of wave is shown.0.20m is the Amplitude of the wave shown.3.0m is the Wavelength.0.6 is the Speed. What is the reason that the duck does not move with the wave in the video? The material is moving through the wave, not the energy The Energy is moving through the wave, not the material. Because of friction Draw the Formula triangle below in your binder. Using the Formula triangle above match the correct formulas to the corresponding variables below. Frequency Wave speed = Wavelength Wave speed / frequency= Wave Speed or Velocity Frequency x Wavelength= Units of measurement match the correct units to the correct terms of measurement. Wavelength Meters (m) Frequency Hertz (Hz) wave speed or Velocity meters (m What is the wavelength of a sound wave with a frequency of 220 Hz if its speed is 340 m ? 0.65 74,800 1.55 Ocean waves are hitting a beach at a rate of 3.5Hz Calculate the speed of the waves if the distance between wave crests is 1.3 meters. 4.55 2.69 0.37 The note A above Middle C on a piano emits a sound wave with a wavelength of 0.77 meters. What is the frequency of the wave? Use 340 m as the speed of the sound wave. 0.002 261.8 441.56 1 2 3 4
