What is the formula for the speed of light using Temperature?

(331.5 + 0.6 x T) m/s

100
A wave that travels along the surface of a medium
Surface Waves
100

A disturbance in matter that transfers energy through the matter.

Mechanical Waves

100

An indication of how high or low a sound is, which is primarily determined by the frequency of the sound wave.

Pitch

100

A wave in which the vibration of the medium is parallel to the direction the wave travels.

Longitudinal Waves

200

What is the other formula for speed?

Speed = Wavelength x Frequency

200

Any speed that is faster than the speed of sound in the medium of interest.

Supersonic Speed

200

A wave in which the medium vibrates at right angles to the direction the wave travels.

Transverse Wave

200

If you were to scream at the top of your lungs in space... would the person 3 feet from you be able to hear your screams?

NO
200

In a transverse wave, how does the medium vibrate?

at right angles to the wave direction

300

Do sound wave oscillate parallel to or perpendicular to the direction in which the wave travels?

parallel

300

A recorder is a woodwind instrument in which the player blows into a tube, setting up a wave in the tube. A musician has 2 recorders. The first one is rather short, and the second one is significantly longer. Which recorder is capable of playing notes with the lowest pitch?

The longer one

300

For waves moving at a constant speed, if wavelength is doubled, what happens to the frequency?

It is halved

300

What is the speed of sound in air that has a temperature of 25 degrees Celsius?

346.5 m/s

300

What sound wave has the longest wavelength?

infrasonic waves

400

A ship blows its horn. Some of the sound waves travel through the air and then hit the water. Will the sound waves travel faster in water or the air?

The Water

400

Are the wavelengths of the man's sound waves longer than, shorter than, or the same size as those of a woman?

The man has lower pitch so it has a longer wavelength.
400

Are the frequencies of the man's sound waves lower or higher than those of a woman?

Since a man has lower pitch, it has longer frequencies.

400

Are the amplitude of the sound waves of a man greater than or less than a woman, when the women is singing louder?

Less than

400

Is the speed of a man's voice or a woman's voice faster?

They are the same

500

During a thunderstorm, the temperature is 10 degrees Celsius. If you see a lightning strike and then hear the thunder 2.0 seconds later, how far away did the lightning strike?

675 m

500

A jet travels through 10 degrees Celsius air at Mach 3. What is its speed in meters per second?

1,012.5 m/s

500

A sound wave traveling through 17 degrees Celsius air has a wavelength of 2 meters. What is the frequency of the sound wave?

170.85 Hz

500
You are driving in a city that has a siren which sounds for 30 seconds every day. You stop at a stoplight and then hear the sound of the siren. The stoplight then turns green, and you start driving. As you speed up, you notice that the pitch of the siren keeps getting higher. Are you driving toward or away from the siren?

Toward the siren

500

An amplifier takes a 30 decibel sound and turns it into an 80 decibel sound. How many times larger is the intensity of the sound waves coming out of the amplifier as compared to the intensity of the sound waves going into the amplifier?

100,000 ties larger after the amplifier as compared to before.
