Wave characteristics Practice Flashcard

Front

What is resonance?

Back

Resonance is the phenomenon that occurs when vibrations traveling through an object match the object's natural frequency, causing it to vibrate with greater amplitude.

Front

What is the formula to calculate the frequency of a wave?

Back

Frequency (f) can be calculated using the formula: f = v / λ, where v is the speed of the wave and λ (lambda) is the wavelength.

Front

If a wave has a speed of 340 m/s and a wavelength of 10 m, what is its frequency?

Back

34 Hz

Front

What is the speed of a wave with a frequency of 50 Hz and a wavelength of 10 m?

Back

500 m/s

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to produce a wave of lesser amplitude, effectively canceling each other out.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and combine to produce a wave of greater amplitude.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles and the spreading out of waves when they pass through small openings.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another, caused by a change in speed.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is the natural frequency of an object?

Back

The natural frequency of an object is the frequency at which it tends to vibrate when disturbed.
