Waves
| Question | Answer |
|---|---|
| What do waves transfer | Energy |
| What do you call the number of waves produced in a given amount of time | Frequency |
| What type of waves do NOT require a medium | Electromagnetic waves |
| How does the sun enable you to see the moon at night | The rays from the sun reflect off the surface of the moon |
| What is the lowest point between each crest of a transverse wave | The trough |
| What is the maximum distance that the particles of a wave’s medium vibrate from their rest position | Amplitude |
| What type of waves travel fastest through empty space | Electromagnetic waves |
| What unit is used to describe the frequency of a wave | Hertz |
| What is the wave speed when waves in the ocean are 8 m apart and pass a boat every 2 s | 4 m/s |
| What is the frequency of a wave | The number of waves produced in a given amount of time |
| A wave made because of destructive interference will have; (pick one) a smaller amplitude- or- a larger amplitude, than the original wave | A smaller amplitude |
| A wave with a larger amplitude than the original wave is formed as a result of; (pick one) constructive interference- or- destructive interference | Constructive interference |
| What is calculated using wavelength (λ) times frequency (ƒ) | Wave speed (ν) |
| What do you call the highest point of a transverse wave | The crest |
| True or False- Amplitude is the distance between two corresponding points on a wave | False, it is wavelength |
| Which type of wave moves parallel to the direction of the disturbance of the particles; A transverse wave or a longitudinal wave | longitudinal wave |
| Amplitude is the maximum distance that the particles of a wave vibrate from their ______ positions | Rest position |
| Sound waves requires a medium- true or false | True |
| Why are sound waves able to diffract around corners better than light waves | Because sound waves have longer wavelengths |
| What type of wave forms when a transverse wave and a longitudinal wave combine | Surface waves |
| If a wave is traveling a certain speed and you double its frequency, what will happen to the wavelength | It will be cut in half |
| What carries more energy; a wave with a shorter wavelength OR a wave with longer wavelength | Shorter wavelength |
| What is wavelength | The distance from any point on a wave to an identical point on the next wave |
| What do you call the speed at which a wave travels through a medium | Wave speed |
| What is it when the crests of one wave overlap the crests of another wave or waves | Constructive interference |
| What is it when two or more waves combine and result in a single wave | Interference |
| When two objects naturally vibrate at the same frequency is called; (pick one) refraction, diffraction, or resonance | Resonance |
| What is it called when a wave changes direction because it runs into an obstacle or an edge | Diffraction |
| What is destructive interference | When the crests of one wave overlap the troughs of another wave |
| Since light is an electromagnetic wave, it does not require a medium through which to travel, so it is transmitted through ________ | Space |
| Sound requires a medium, so it cannot be transmitted through _______ | Space |
| The number of vibrations per second of a wave | Frequency |
| True or False- The material through which the wave travels does not move with the energy | True, waves only carry energy |
| Which will carry more energy; high-frequency or low-frequency waves | High frequency waves |
| A Transverse wave moves (perpendicular OR parallel) to the direction of the disturbance of the particles | Perpendicular |
| What occurs when a wave strikes a barrier and reverses direction | Reflection |
| In refraction, what happens to a waves speed and direction when it enters a different medium | Its speed and direction change |
| When you put your arm in a pool of water, your arm appears bent because of what | Refraction |
| Frequency, amplitude, wave speed, and wavelength, are all _______________ of waves | Properties of waves |
| What is a pattern of vibration that simulates a wave that is standing still | A standing wave |
| What is any disturbance that transmits energy through matter or empty space | A wave |
| Which has longer wavelengths; sound or light | Sound waves |
| In surface waves, how do the particles move | In circles rather than up and down |
| Frequency is measured by counting how many waves pass by in a certain amount of time; if two waves go by in 10 s, what is the frequency? | 2 /10 s = 0.2 Hz. |
| Radio waves, microwaves, and X rays are examples what type of waves | Electromagnetic waves |
| What do waves carry- energy OR matter | Energy |
| What type of waves have compressions and rarefactions | Longitudinal |
