Assuming an electromechanical wave not much. The speed of the wave depends on the medium that the wave is passing through. In a vacuum it is the speed of light, through something else a lesser speed. The wavelength stays the same and the frequency stays the same.
That can't happen. The product of (frequency) times (wavelength) is always the wave's speed.
There's no way to increase frequency without also decreasing the wavelength.
If the wave happens to encounter a different medium ... like a sound hitting jello or a
beam of light hitting air ... then its speed changes while the frequency remains constant,
which means that the wavelength changes in the new medium.
Well, if it's an electromagnetic wave, then you just disproved physics, congratulations.
velocity increases
velocity increases
It decrease in wave speed.
frequency increases
wavelength decreases
When the temperature increases as a result of reaction, as specified here, the reaction is exothermic.
When a nucleus emits a beta particle (electron) it is a result of neutron decay. This decay will also release an antineutrino and a proton is left which increases the atomic mass by one thereby changing the element.
It increases the collisions that result in a reaction. or it increases the kinetic energy of the molecules.
effect
firstly boron due to its small size has highest electronegativity in the group.Next Al , has larger size and atomic radii so electronegativity decreases. But in Ga due to the presence of 10 d-electrons , the shielding effect gets reduced. As a result the attraction due to the nuclear charge increases. The same happens with In and Tl. By Ashank

the frequency of the wave increases.
the frequency of the wave increases.
This is not true practically. Theoretically speaking as velocity increases with wavelength remains constant, then frequency has to increase accordingly. Since the formula for velocity is given as: velocity of the wave v = frequency (nu) * wavelength (lamda). In reality the characteristic, namely, frequency remains constant when the speed of the wave changes as it traverses in different medium.

As the basic formula of all types of waves is (Velocity of a wave=the product of the wavelength of it and its frequency). In this case, frequency of a certain wave is constant and the velocity is decreasing. And as the velocity is directly proportional to the wavelength, the wavelength of the wave shortens as a result.
You get the velocity of the wave.
The velocity of the wave is equal to the product of the frequency and the wavelength. Therefore, for constant wavelength, the wavelength will decrease. Furthermore, for an electromagnetic wave, the energy of the wave E = hf, where h is Planck's constant and f is the frequency, the energy of the wave decreases as frequency decreases (and the velocity within a vacuum is always constant and equal to c).
The band gap of the semiconductor decreases as the temp. increases, and with formulae E = hv (which is inverse of the wavelength) as a result wavelength increases. reference: http://ecee.colorado.edu/~bart/book/eband5.htm
With a water wave, an increase in the length of the wavelength will result in a decrease in the frequency of the wave. We could say that there is an inverse relationship between the frequency and the wavelength. As one increases, the other decreases, and as one decreases, the other increases.
