Question

How can we determine the velocity from wavelength, frequency and period in terms of waves?

Answer 1

To determine velocity from wavelength, frequency, and period in terms of waves, we can use the following formulas:

1. Velocity = Wavelength × Frequency: This formula relates the velocity (v) of a wave to its wavelength (λ) and frequency (f). It states that the velocity of a wave is equal to the product of its wavelength and frequency.

2. Velocity = λ / T: This formula relates the velocity (v) of a wave to its wavelength (λ) and period (T). It states that the velocity of a wave is equal to the wavelength divided by the period.

Here's a breakdown of how you can use these formulas:

1. If you have the wavelength (λ) and frequency (f), you can use the formula v = λ × f to determine the velocity (v) of the wave.

2. If you have the wavelength (λ) and period (T), you can use the formula v = λ / T to determine the velocity (v) of the wave.

Remember to use consistent units for the variables. For example, if the wavelength is given in meters (m), the frequency should be in hertz (Hz), and the velocity will be in meters per second (m/s).

It's important to note that the formulas above assume that the wave is traveling in a uniform medium and that there are no other factors affecting the wave's velocity.
