A student measures the frequency and the wavelength of a wave.
Which calculation gives the speed of the wave?
frequency+wavelength\text{frequency} + \text{wavelength}frequency+wavelength
wavelength÷frequency\text{wavelength} \div \text{frequency}wavelength÷frequency
frequency÷wavelength\text{frequency} \div \text{wavelength}frequency÷wavelength
frequency×wavelength\text{frequency} \times \text{wavelength}frequency×wavelength
