waves 3 - f & T calculations

Front

What is the formula to calculate the period (T) of a wave?

Back

T = 1/f, where T is the period in seconds and f is the frequency in hertz.

Front

What is the relationship between frequency (f) and period (T)?

Back

Frequency is the reciprocal of the period: f = 1/T.

Front

If a radio station broadcasts at a frequency of 90.1 MHz, what is the frequency in Hz?

Back

90.1 MHz = 90.1 x 10^6 Hz.

Front

How do you calculate the frequency of a wave if you know the number of cycles and the time taken?

Back

Frequency (f) = Number of cycles / Time (in seconds).

Front

What is the frequency of a tadpole vibrating 30 times in 5 seconds?

Back

Frequency = 30 cycles / 5 seconds = 6 Hz.

Front

What is the period of a wave with a frequency of 6 Hz?

Back

Period (T) = 1/f = 1/6 seconds = 0.167 seconds.

Front

How do you convert MHz to Hz?

Back

Multiply the value in MHz by 1,000,000 (10^6).

Front

What is the average speed of a point on a wave if the frequency triples?

Back

If the frequency triples, the average speed also triples, assuming the wavelength remains constant.

Front

What is the definition of a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is perpendicular to the direction of the wave's travel.

Front

What is the formula for wave speed (v)?

Back

Wave speed (v) = frequency (f) x wavelength (λ).
