I read that speed is directly proportional to wavelength in a medium. so does it mean that gamma is the slowest in air compared to the rest of the waves?
That is right, but the dependence is complicated and no where near "linear". In good approximation, all wavelengths have the speed of c in air, which is the same as they have in a vaccum.Jasso said:I think what Simon Bridge is saying is that the speed of propagation through a medium is dependent on frequency, with emphasis on "through a medium".
The speed of electromagnetic waves is directly proportional to the magnitude of their wavelength. This means that as the magnitude of the wavelength increases, the speed of the waves also increases. Similarly, as the magnitude of the wavelength decreases, the speed of the waves decreases.
The speed of electromagnetic waves changes with different wavelengths in a direct proportion. This means that as the wavelength increases, the speed also increases and as the wavelength decreases, the speed decreases.
Yes, the speed of electromagnetic waves is directly affected by the magnitude of their wavelength. A longer wavelength will result in a higher speed, while a shorter wavelength will result in a lower speed.
No, the speed of electromagnetic waves cannot be directly measured based on the magnitude of their wavelength. It is a constant value, which is approximately 3 x 10^8 meters per second in a vacuum. However, the wavelength can be used to calculate the frequency of the wave, which can then be used to calculate the speed using the formula speed = frequency x wavelength.
If the magnitude of the wavelength is doubled, the speed of electromagnetic waves will also double. This is because they have a direct proportionate relationship, meaning that any change in one will result in a corresponding change in the other.
