Question

Parts of A Wave. Use the word bank below to identify the parts of a wave in this diagram. Type the word next to the letters below. Each correct answer is worth 1 pt. A. ________________________ B. ________________________ C. ________________________ D. ________________________ E. ________________________ 2. Relationship between wavelength and frequency A. Describe the relationship between wavelength and frequency when frequency is increased. (2pts) B. Describe the relationship between wavelength and frequency when frequency is decreased. (2pts) Hint: Connect 2 crests together to see wavelength on both waves.

Answer 1

Explanation:

A = Wavelength

The distance between two consecutive crest or trough is wavelength

B = Amplitude

The maximum distance covered by the particles of a wave

C = Rest postion/equilibrium

When there is no disturbance in the medium

D = Trough

It is the displacement in negative direction

E = Crest

It is the displacement in positive direction

(A) The relationship between the wavelength and frequency is given by :

$f=\dfrac{v}{\lambda}$

There is an inverse relationship between wavelength and frequency.

(B) $\lambda=\dfrac{v}{f}$

When the frequency is decreased, the wavelength of a wave increases.
