Let us list some of the factors, which could possibly influence the speed of wave propagation:
motion of the source and/or observer.

5 Let us list some of the factors, which could possibly influence the speed of wave propagation: (i) nature of the source (ii) direction of propagation. (iii) motion of the source and/or observer. (iv) wavelength. (v) intensity of the wave. On which of te factors, if any, does,depend?: the speed of light in a medium (say, glass or water)

List three factors which influence water potential.

List the factors which influence ionisation energy. actions.

When can a charge act as a source of electromagnetic wave? How are there directions of electric and magneitc field vectors, in an electromagnetic wave related to each other and to the direction of propagation of the wave? Which physical quantity, if any has the same value for waves belonging to the differnt parts of the electromangetic spectrum?

What should be the order of magnitude of the minimum fequency of electromagnetic waves that could be used to detect the presence of a bird 0.1m long? From what sources of electromagnetic radiation would you be able to generate radiation of these wavelengths?
