What Does a Wave Travel Through and Write a Definition of Medium?
• When a wave travels through a medium the particles of the medium vibrate. • A Medium is whatever the wave is travelling through.
What Do particles transfer when they vibrate?
• When particles vibrate they transfer energy.
Write a Definition of The Amplitude?
• Amplitude is the maximum displacement from the waves resting position.
Write a Definition of the Wavelength and How do you work out the wavelength?
• The wavelength is the distance from 1 point on a wave to the same point. • Its from 1trought of a wave to the other trough.
Write a Definition of Frequency and what’s it measured in?
• Frequency is the number of vibrations per second made by the wave. • Frequency is Measured in Herts (Hz) 1 Hz is 1 wave per second.
Write a Definition of a Period?
• Period is the amount of time it takes 1 complete wave to pass a certain point.
Name the 2 Different types of waves?
• 1) Longitudinal Waves. • 2) Transverse Waves.
Write a Definition of a Ray?
• A Ray is a straight line showing the path along which a wave moves.
What are the Main uses of Transverse Waves and How fast do transverse waves travel?
• Main Uses:Light,Radio,Microwaves and Gamma waves. • Transverses Waves travel 300 million m/s
What Happens in a Transverse Waves and How Do they move in a direction?
• In Transverse waves Particles vibrate in a direction perpendicular to the direction of propagation of the wave.
What are formed in transverse Waves and where do they form?
• Peaks and Troughs are formed in these waves. • These waves are formed on the surface of solid and liquids.
What’s The main use of longitudinal waves and how do particles travel?
• The Main use: Sound. • Particles vibrate in a direction Parallel to the direction of propagation of the wave.
What is formed in longitudinal waves and where is it formed?
• Compression and rarefaction is formed. • Longitudinal waves are formed in solids liquids and gases.
What’s the equation of a period of a wave?
• 1 ÷ Frequency
What’s the equation of Wave speed?
• Frequency (Hz) x Wavelength (m)
In 4 Steps how do You Calculate waves on water (PRATICAL)
• 1) Place a ruler onto a piece of card underneath the tank and turn on the power supply. • 2) Measure the distance of 10 consecutive waves. • 3) Divide this number by 10 to calculate 1 wave length. • 4) To calculate Frequency you would time how many waves pass a point a second.
In 5 Steps how do you calculate waves in air (PRATICAL)
• 1) Measure the Length of the string at the second harmonic this will be 1 wavelength. • 2) Set The frequency so jest 1 wave is on the string. • 3) Record the frequency. • 4) Increase the frequency until 2 waves arrear. • 5) Repeat once more.
Write a Definition of Electromagnetic Spectrum?
• Electromagnetic spectrum is a Continuous spectrum of all the possible wavelength of Electromagnetic waves.
What Do electromagnetic waves Transfer and what type of waves are electromagnetic waves?
• Electromagnetic waves transfer energy from a sauce to an absorber. • Electromagnetic Waves are transverse waves.
What Do all electromagnetic waves travel at and what are they grouped on?
• All electromagnetic Waves travel at the same speed. • They are grouped based on frequency and wavelength.
Name the 7 different types of waves in the electromagnetic spectrum in order?
• 1) Radio waves. • 2) Microwaves • 3) Inferred waves. • 4) Visible Light. • 5) Ultra violent Radiation. • 6) X-Ray • 7) Gamma radiation.
What’s The mnemonic To Remember the 8 common uses of Radio waves?
• Big - Broadcasting (Radio ,Tv) • Satellites - Satellites (Communication, GPS , Internet) • Can - Communication (Mobile Phones Wi-fi , Bluetooth) • Help - Healthcare (MRI Scanners) • Make - Military (Radar) • Space - Space (Astromancy and space probes) • Really - Remote control (Garage doors and remote control) • friendly - Factories (Industrial heating) • Big Satellites can help make space really friendly
Name all The uses of Microwaves?
• Microwaves are used to heat up food and water. • Its also used in radar, Telephone and other signals.
Name All the uses of Infrared Radiation?
• Transmits heat from sun, Radiators and fires. • And Used in heat redaction to warm up your house.
