Front

What is the phenomenon called when waves bend around an object, such as through a doorway?

Back

diffraction

Front

What term describes how high or low a sound is, which depends on the frequency?

Back

pitch

Front

What is a disturbance that transfers energy from one place to another without transferring matter?

Back

Front

What is the relationship between frequency and pitch in sound waves?

Back

Higher frequency results in a higher pitch.

Front

What is the difference between a longitudinal wave and a transverse wave?

Back

In a longitudinal wave, particles move parallel to the direction of wave propagation, while in a transverse wave, particles move perpendicular to the direction of wave propagation.

Front

What is the formula for calculating the speed of sound in air?

Back

Speed of sound = 331.3 m/s + (0.6 m/s/°C) * temperature in °C

Front

What is the effect of temperature on the speed of sound?

Back

The speed of sound increases with an increase in temperature.

Front

What is the term for the maximum displacement of particles in a wave from their rest position?

Back
