True or False? 20 questions
Question 1 Sound is a transverse wave
Question 2 Waves are vibrations
Question 3 Amplitude is the maximum distance from the normal of a wave
Question 4 Frequency is measured in Lambda ( )
Question 5 Radio 1 FM (88-91MHz) has a shorter wavelength that BBC 5 Live MW ( kHz)
Question 6 You cannot reflect all waves
Question 7 All waves are visible
Question 8 Diffraction is where waves change direction due to a change in speed
Question 9 A Tsunami is made of lots of little waves creating one big wave as in interference of waves
Question 10 In sound the higher the frequency the higher the note
Question 11 A wave will travel faster in a more dense material
Question 12 Gamma radiation has the highest frequency of the waves in the electromagnetic spectrum
Question 13 All waves of the electromagnetic spectrum can pass through the body
Question 14 In stars a red giant is hotter than a blue dwarf and has a higher frequency
Question 15 Waves can go around corners
Question 16 Digital signals have a range of frequencies
Question 17 Optical fibres use dispersion to transfer from one end to the other
Question 18 When sunlight passed through a raindrop it splits into a spectrum of colours. This is because sunlight is made up of different frequencies and wavelengths.
Question 19 A “ noisy” wave is a bad thing. Noise is interference but can be corrected.
Question 20 Write down as many uses of each type of wave as you can
True or False? 20 questions. Question 1 Sound is a transverse wave False its longitudinal!
True or False? 20 questions. Question 1 Sound is a transverse wave.
Waves. Wave: a disturbance that transfers energy from place to place. Medium: the material through which the wave can pass. Waves are classified by: 1.
The electro-magnetic spectrum. Key facts All the waves travel at the same speed – around km/s.
Bellringer What is the relationship between an object and the sound waves it creates during a sonic boom?
By Will B. Electromagnetic waves The different waves that make up the electromagnetic spectrum are as follows in order of increasing frequency; Radio.
P1.5 The use of waves P1.5 The use of waves for communication and to provide evidence that the universe is expanding Electromagnetic radiations travel.
The Behavior of Waves. Reflection Reflection occurs when a wave strikes an object and bounces off of it.Reflection occurs when a wave strikes an object.
Chapter 10 Waves. Chapter 1o Section 1 The Nature of Waves.
Waves Energy is sometimes transferred from place to place by traveling in waves. Sound and light travel in waves. Some substances transport energy through.
Which of the following waves requires a material medium through which to travel? (a) Sound (b) Television (c) Radio (d) X ray Q1.
Fundamentals of Light. Light Light is not only comprised of the light we can see (visible light), but also other types of light waves, called EM waves.

Waves, Sound, and Light Chapter 3. Bell Work 11/29/10 Please get a new bell work sheet. Write each statement then decide if they are true or false, if.
EM Waves The sound wave is moving through air and the water wave through water. Without matter to transfer the energy, they cannot move. Sound and Water.
Waves and Energy Physics, Grade 8. Types of Waves Mechanical Waves need matter (medium) to travel through Mechanical Waves need matter (medium) to travel.
Characteristics of waves Pg. 47. Daily Science pg. 48 Name the two main types of waves. What are the two sub categories of waves? Draw the two types of.
The Electromagnetic Spectrum The Nature of Electromagnetic Waves Waves of the Electromagnetic Spectrum Producing Visible Light Wireless Communication Table.
Consider the Following ??. What is Light Electric Field... Is the space around an electric charge, it does not have mass. It is not matter It exerts.
UNIT 5: VIBRATIONS, WAVES & SOUND. Waves and Oscillations Pendulum swinging back and forth shows how oscillations can create waves.
The movement of heat in the atmosphere causes temperatures to change, winds to blow, and rain to fall.
UNIT 5: VIBRATIONS, WAVES & SOUND. SIMPLE HARMONIC MOTION Position vs. time graph for an object shows how oscillations can create waves.
