Festus High School Spring Review 5

Front

Why does sound travel faster through a solid than a gas?

Back

Sound travels faster through a solid because solid molecules are packed tightly, allowing sound waves to transmit more quickly.

Front

What is the relationship between wavelength and frequency?

Back

The longer the wavelength, the lower the frequency.

Front

What is frequency in the context of waves?

Back

Frequency is the number of wavelengths that pass a point each second.

Front

How do you calculate the speed of a wave?

Back

Speed of a wave = frequency × wavelength.

Front

What is the speed of a wave with a frequency of 46 Hz and a wavelength of 1.7 meters?

Back

78.2 m/s.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves affect one another positively, producing a single wave of greater amplitude.

Front

What is the definition of amplitude in waves?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the particle displacement is parallel to the direction of wave propagation, while in transverse waves, it is perpendicular.

Front

What is a wave period?

Back

The period is the time it takes for one complete cycle of a wave to pass a given point.

Front

What is the formula for calculating wave frequency?

Back

Frequency (f) = 1 / period (T).
