| Question | Answer |
|---|---|
| Sound travels as what type of wave | LONGITUDINAL |
| The speed of sound depends on | DENSITY TEMP ELASTICITY |
| The speed of sound will travel the fastest in what Fahrenheit temperature | WARMER |
| The pitch of sound depends on | FREQUENCY |
| Sounds of frequencies below 20 Hz are called | INFRA-SOUND |
| Sounds of frequencies above 20,000 Hz are called | ULTRASOUND |
| Change in frequency of a sound wave due to the motion of an object is called | DOPPLER |
| What happens to the siren's sound as it is racing towards you | FREQUENCY WILL INCREASE |
| The intensity of sound is measuring its amount of | ENERGY |
| The science of sound is called | ACOUSTICS |
| A wave travels through a medium because | WAVE ENERGY TRAVELS PARTICLE TO PARTICLE |
| Musical instruments have a certain sound quality or | TIMBRE |
| Stringed instruments you change the pitch by changing the | LENGTH THICKNESS TIGHTNESS |
| What system is used to detect objects underwater | SONAR |
| Waves through water in which intense cleaning takes place uses what process | ULTRASONIC |
| Process in medicine where they send sound waves through the body to get an image | ULTRASOUND |
| A disturbance that transfers energy from place to place is called a | WAVE |
| The bending of waves due to a change in speed is called | REFRACTION |
| The bending of waves around the edge of a barrier is known as | DIFFRACTION |
| The interaction between two waves that meet is called | INTERFERENCE |
| . Waves combine to make a wave with larger amplitude in a process called | CONSTRUCTIVE INT |
| When an incoming wave combines with a reflected wave in such a way that the combined wave appears to be standing still, the result is a | STANDING WAVE |
| What occurs when vibrations traveling through an object match the object’s natural frequency | RESONANT FREQUENCY |
| Frequency is measured in units called | Hz |
| When a wave hits a surface through which it CANNOT pass and bounces back, | REFLECTION |
| Waves combine to produce a smaller or zero-amplitude wave | DESTRUCTIVE INT |
| Why do you see lightning from a distant storm before you hear thunder | LIGHTNINGS FASTER |
| Light waves are what type of wave | TRANSVERSE |
| Electromagnetic waves differ from other waves because they | CAN TRAVEL IN A VACUUM |
| The electromagnetic waves with the lowest frequency and the longest wavelength are | RADIO |
| The Radio waves with the highest frequencies are | MICROWAVES |
| Characteristics of infrared rays | CAN’T BE SEEN / FELT AS HEAT / FREQ LOWER THAN RED |
| Electromagnetic waves with the highest frequencies are | GAMMA |
| The electromagnetic spectrum does not include | SOUND WAVES |
| The waves responsible for tanning and for vitamin D production are | ULTRAVIOLET |
