Radiowaves and gamma rays both are transverse in nature and electromagnetic in character and have the same speed in vacuum.In what respects are they different?

What is meant by the transverse nature of electromagnetic waves? Draw a diagram showing the propagation of an electromagnetic wave along the X-direction, indicating clearly the directions of the oscillating electric and magnetic fields associated with it.

In what respect is Huygens' wave theory of ight similar to Maxwell's electromagnetic theory ?In what respect are the two theories different?

What is the ratio of speed of infrared rays and ultraviolet rays in vacuum?

Two different gases have exactly the same temperature. Does this mean that their molecules have the same r.m.s. speed?

In these question, a statement of asertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. Asssertion:When an electromagnetic wave enters an optically denser medium ,its frequency remains the same but its waelength and speed decrease Reason:The frequency is an inherent charactgerstic of the radiation.The wavelength and hence the speed decreases by a factor n,where n is refreactive index of the medium

Electromagnetic spectrum Electromagnetic waves are coupled time varying electric and magnetic fields, propagating in space, with the speed very close to that of light (3xx10^8 ms^-1) . An the orderly distribution and classification of electromagnetic waves according to their frequency or wavelength is called electromagnetic spectrum. electromagnetic waves inclued visible light, ultraviolet waves, infra red waves, X-rays, gamma-rays, microwaves and radiowaves. Which of the following belongs to the electromagnetic spectrum
