Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A wave with a large wavelength will have a ____ frequency and ____ energy
A
high, low
B
high, high
C
low, high
D
low, low
Explanation: 

Detailed explanation-1: -From this equation you can see that as wavelength increases, the frequency of the wave decreases. The energy associated with a wave is directly proportional to its frequency. Hence, the higher the frequency, the shorter the wavelength and the higher the energy of the wave.

Detailed explanation-2: -The energy of a wave is directly proportional to its frequency but inversely proportional to its wavelength. That means the greater the energy, the larger the frequency and the shorter the wavelength. Given the relationship between wavelength and frequency, short wavelengths are more energetic than long wavelengths.

Detailed explanation-3: -As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic.
