longitudinal and transverse waves longitudinal waves Longitudinal waves have rarefactions which is when the particles are spread out. Compressions are when the particles have been squashed together When sound travels, it travels in a longitudinal wave... Yordanos Gebre
Sound waves Sound is a longitudinal wave – the direct of the oscillation is parallel to the direction in which the wave is traveling All sounds are produced by objects that are vibrating. These sounds travel outwards, from the so... Alex Scaife
Nature of waves Newton described light as particles called corpuscles. Different colours were due to corpuscles of different sizes. He explained reflection in terms of the corpuscles bouncing off of reflective surfaces. elisesophie97

Unit 4: Oscillations and Waves 4.1 Oscillations  Simple Harmonic Oscillations  Oscillations are periodic motions which centre around an equilibrium position.  Special Harmonic Motion is a special type of oscillation, i.e.: ... Phoebe CHAN
Waves - The Electromagnetic Spectrum The Electromagnetic Spectrum The electromagnetic spectrum is the range of all possible frequencies of electromagnetic waves and radiation  The spectrum ranges from Radio waves with relatively small frequencies of... ed.wilson89
What is sound?How do we hear? Sound & hearing Pitch Pitch is the rate at which sound waves are produced or how high or low a sound is. The higher the pitch the rate at which sound waves are produced increases. Some ways of changing the pitch on a guitar are tight... M Ro
Waves and their properties Sound waves are longitudinal. The direction of vibration of individual air molecules is the same as the direction of wave. In transverse waves the direction of vibration is at a right ang... Piano Jem
Waves - Longitudinal Waves Longitudinal Waves Longitudinal waves are waves where the oscillations of the wave are parallel to the direction of travel Mechanical longitudinal waves are also known as compression waves because they compress the pa... ed.wilson89
Sound waves - Example 1 Maria was watching the waves as they hit the boats in the bay. She noticed that they made a complete up and down vibration cycle in 8 seconds. The boats where 20 meters apart, and when one boat was at a high position,... ed.wilson89
16.1 Sounds Sounds Properties of Sound: Sound waves are longitudinal waves caused by vibration that travel through a medium (object) The waves in the air are spread in all directions away from the source. When the waves reaches y... Leen ALdash

Waves - Transverse Waves Transverse Waves With a transverse wave, the oscillations travel perpendicular to the direction of travel Examples of transverse waves are light waves, waves in the sea and ripples in a pond ed.wilson89
Science notes ‘All waves can tranfer energy from one point to another without transferring any matter.’  Waves can transfer energy through solids, liquids and gases as well as empty spaces(vacuums) The two types of waves are l... emily stratford
Sound The loudness of a sound is linked to the size of the vibrations. Large vibrations produce louder sounds. Quiet sounds are caused by small vibrations The number of vibrations made in one second is called the frequency.... Alex Scaife
Waves - Polarization Polarisation Polarization is a property of waves that can oscillate in more than one orientation - i.e. light waves  Polarized light waves are light waves that only have vibrations in one orientation  ed.wilson89
Physics Sound waves are longitudinal waves that must pass through a medium, such as air. Echoes are reflections of sounds. The frequency of ultrasound is above 20 kHz. Ultrasound is useful for cleaning and also used for check... Thulasika Sithambaralingam
Untitled DEFINITIONS Waves with the partcles oscillating parallel to the wave motion are called Lonfitudinal wave.  Those with oscillations perpendicular to the direction of progression are called Transverse waves. Moveme... Karen Mosa
waves waves transfer energy in the direction they travel  when waves travel through a medium, the particles of the medium oscillate and transfer between each other . But overall, the particles stay in the same place - ... mahnoor kayani

Wave speed Wave speed (m/s) = frequency (Hz) x wavelength (m) v = f (Weird upside-down y thing) Wave speed (m/s) frequency (Hz) x wavelength (m) Step 1: Write down what you know, with units.  frequency = 20Hz wavelength = 3... lily bevan
Nature of Waves- concise notes Transverse and Longitudinal waves In all types of progressive waves, energy is transferred without a transfer of matter. Transverse- Particles oscillate in a direction perpendicular to the direction of energy transfer... Rhiannon Pritchard
Sound Sound Echo: an echo is a reflection of sound from a boundary/ barrier. Equation: S=A/t. Ultrasound: a sound wave with a frequency higher than 20,000Hz. Uses: Scanning unborn babies/internal organs, detecting cracks in... John Carroll
