Question

What is the wave velocity if the wave length is 100 cm and the frequency is 2 Hz?

200 cm per second

102 cm per second

150 cm per second

100 cm per second

Answer 1

The wave velocity can be calculated using the formula:

\[
v = f \times \lambda
\]

where \( v \) is the wave velocity, \( f \) is the frequency, and \( \lambda \) is the wavelength.

Given:

- Frequency (\( f \)) = 2 Hz
- Wavelength (\( \lambda \)) = 100 cm

Plugging in the values:

\[
v = 2 \, \text{Hz} \times 100 \, \text{cm} = 200 \, \text{cm/s}
\]

So, the wave velocity is **200 cm per second**.
