Answer : The correct option is, amplitude = 14 cm; wavelength = 7 cm; period = 12 seconds
Explanation :
The amplitude, wavelength and time period of three types of waves.
As we know that energy of a wave is given as :
[tex]E=\frac{h\times c}{\lambda}[/tex]
From this we conclude that the energy of a wave is inversely proportional to the wavelength.
i.e [tex]E\propto \frac{1}{\lambda}[/tex]
As the the wavelength increases, the energy will decreases and vice-versa.
So, the wave have less wavelength will have the greatest energy.
Also, there is a relation between the energy and the amplitude wave. That is the energy of a wave is directly proportional to the square of amplitude.
i.e. [tex]E\propto(Amplitude)^2[/tex]
That means the wave have maximum amplitude will have maximum energy.
Hence, the correct option is, amplitude = 14 cm; wavelength = 7 cm; period = 12 seconds.
