Q/ The wavelength of a wave in a medium increases as a result of which of the following changes in parameters? 

A. an increase in frequency 

B. a decrease in frequency increase in speed 

D. a decrease in speed 


Expert Answer

Step 1

The formula of wavelength: •1= Wavelength •v = Speed of the wave •f = Frequency of the wave

Step 2

According to the formula, 1. The frequency is inversely proportional to the wavelength, therefore, to increase the wavelength there should be a decrease in the frequency. 2. The speed is directly proportional to the wavelength, therefore, to increase the wavelength there should be an increase in the speed.
