Step 1 help_outlineImage TranscriptioncloseThe formula of wavelength: •1= Wavelength •v = Speed of the wave •f = Frequency of the wave fullscreen
Step 2 help_outlineImage TranscriptioncloseAccording 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. fullscreen
