Sound Waves
What wave property determines the pitch of a sound?
What is the frequency?
What wave property determines the color of light?
What is the frequency?
What is the electromagnetic spectrum?
What is the spectrum that organizes light by frequency and wavelength?
What is meant by the term ultrasonic?
What are sound waves greater than 20,000Hz? Ultra means "beyond" or "extremely"
True or false: Sound requires a medium to travel from place to place.
What is true?
What wave property determines the volume of a sound?
What is the amplitude?
What wave property determines the brightest of light?
What is frequency measured in?
Hertz
What is meant by the term infrasonic?
What are sounds that are below 20 Hz. Infra means "below" or "Under"
True or false: Light requires a medium to travel from place to place.
What is false?
What is the relationship between frequency and wavelength for sound waves?
Frequency and wavelength have an inverse relationship. Waves with a longer wavelength have a lower frequency, and waves with a shorter wavelength have a higher frequency.
When the slinky is shaken up and down to make a transverse wave, the slinky can be a good analogy for light. This is because the slinky coils move perpendicular to the direction of the wave energy.
What is the visible spectrum?
What are the frequencies of light humans are able to see.
What type of wave is a light wave?
What is a transverse wave?
A dog whistle generates a sound with an ultrasonic pitch so that dogs are able to hear the whistle, but humans are not. Which of the following frequency values is most likely the frequency of a dog whistle:
10 Hz
15,000Hz
25,000Hz
50,000Hz
What is 25,000Hz
What type of wave model is a sound wave?
What is a longitudinal wave model?
Which color in the visible spectrum has the highest frequency?
What is violet?
Which common source has the highest frequency?
What is radioactive?
What is the definition of audible frequency?
The sound range that humans are typically able to hear.
True or false: Only sound propagates/travels in all directions
What is false- Sound and light propagate/travel in all directions.
What wave characteristics need to change to make a sound have a softer volume and a higher pitch?
The sound needs to have a smaller amplitude and a smaller wavelength/higher frequency.
Which color in the visible spectrum has the lowest frequency?
What is red?
Which light waves have the smallest wavelength?
What are radio waves?
True or false: Light and sound waves move spherically
What is true?
Which 3 animals are able to hear ultrasonic frequencies?
Bats, Beluga Whales, and Dolphins
