the wave length will increase
In this case, the wavelength increases. The wavelength, multiplied by the frequency, is equal to the speed of the wave - and in most types of waves, the speed is more or less independent of the frequency.
When wavelength decreases, frequency increases, and when wavelength increases, frequency decreases. The product of (wavelength) times (frequency) is always the same number ... the speed of the wave. So when one of them changes, the other one must change in the opposite direction in order for their product to remain unchanged.
If the frequency of the light wave is decreased by a factor of 2, the wavelength will double. This is because the speed of light remains constant in a given medium, so as frequency decreases (and energy decreases), wavelength increases to maintain the speed of light.
If the frequency of a wave is left unchanged, the wavelength will also remain constant. Wavelength and frequency are inversely proportional, so they always adjust together to maintain the speed of the wave.
The product of (frequency) times (wavelength) is always the same number. (It happens to be the speed of the wave.) So if one of them doubles, the other one gets decreased by half.
In this case, the wavelength increases. The wavelength, multiplied by the frequency, is equal to the speed of the wave - and in most types of waves, the speed is more or less independent of the frequency.

The freequency of a wave is increased when the wavelength is decreased. This is because the product of the frequency and the wavelength are a constant that determines the speed of the wave c=fw.
If you are talking about an electromagnetic wave; energy is proportional to frequency (E=hf), and frequency is inversely proportional to wavelength (wavelength equals velocity divided by frequency). So when the wavelength is increased, the energy is decreased.
If the frequency of the light wave is decreased by a factor of 2, the wavelength will double. This is because the speed of light remains constant in a given medium, so as frequency decreases (and energy decreases), wavelength increases to maintain the speed of light.
Whatever the wavelength and frequency happen to be, their product is always equal to the speed.
It would change, depending on how much the frequency and the wavelength changes. It varies based on v = fλ.
If the frequency of a wave is left unchanged, the wavelength will also remain constant. Wavelength and frequency are inversely proportional, so they always adjust together to maintain the speed of the wave.
The product of (frequency) times (wavelength) is always the same number. (It happens to be the speed of the wave.) So if one of them doubles, the other one gets decreased by half.
IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).
Diffraction, more diffraction if wavelength is increased (or frequency decreased)
No, frequency and wavelength are inversely related in a phenomenon called the wavelength-frequency relationship. As the wavelength increases, the frequency decreases, and vice versa. This relationship is described by the equation: Speed = Frequency x Wavelength.
