Properties of Waves
Science Unit 3 Lesson 1
| Question | Answer |
|---|---|
| What are types of waves? | Light & sound |
| What is a wave? | A disturbance that carries energy and travels in a repeating pattern |
| What is a disturbance that carries energy and travels in a repeating pattern? | A Wave |
| What causes disturbances that cause waves? | Vibrations |
| What do vibrations make? | Waves |
| What is one complete wave? | One back and forth motion |
| What is carried by vibrations/waves? | Energy |
| Which waves can travel through empty space? | Light |
| What do sound waves need to pass through? | A medium |
| What is a medium? | An material a sound wave must pass through |
| What travels faster light or sound waves? | Light |
| What is the greatest height of a wave? | Amplitude |
| What is amplitude? | The highest part of a wave |
| Which amplitude makes a louder sound? | A high amplitude |
| What is a wavelength? | The distance between similar point on a wave |
| What is the distance between similar points on a wave? | Wavelength |
| What is frequency? | The number of wave repetitions in a certain amount of time. |
| What is the number of wave repetitions in a certain amount of time? | Frequency |
| High frequency waves have a ———— pitch | high |
| If a wave is more frequent, waves will be ———- | shorter |
| What is the difference between amplitude and frequency? | Amplitude is how high a wave travels, frequency is how many times waves travel in a certain amount of time |
| What is a transverse wave? | Moves perpendicular to the direction of particles |
| What kind of waves move perpendicular to the direction of particles? | Transverse |
| What is a crest? | The top point of a wave |
| What is a trough? | The bottom point of a wave |
| What is the top point of a wave called? | Crest |
| What is the bottom point of a wave called? | Trough |
| What is a longitudinal wave? | moves in the same direction as the particles |
| What kind of waves move in the same direction as the particles? | Longitudinal |
| What are waves | A transfer of energy |
| What does transfer mean | To relocate |
| What word means relocate? | Transfer |
