Question

lesson 27 - properties of waves
which two have an inverse relationship?
□ frequency
□ wavelength
□ energy

Explanation:

The wave speed formula is \( v = f\lambda \), where \( v \) (speed) is constant for a given medium. Rearranged as \( f = \frac{v}{\lambda} \) or \( \lambda = \frac{v}{f} \), this shows frequency (\( f \)) and wavelength (\( \lambda \)) are inversely related: as one increases, the other decreases. Energy is directly proportional to frequency (\( E = hf \)), so no inverse relation with frequency/wavelength.

Answer:

frequency, wavelength
