N an electromagnetic wave in free space, the electric and magnetic fields are A. parallel to one another and perpendicular to the direction of wave propagation. B. parallel to one another and parallel to the direction of wave propagation. C. perpendicular to one another and perpendicular to the direction of wave propagation. D. perpendicular to one another and parallel to the direction of wave propagation.

C. Perpendicular to one another and perpendicular to the direction of wave propagation.

Explanation:

Electromagnetic waves are the waves which arise due to vibrations of both electric and magnetic fields. In electromagnetic waves, the electric and magnetic fields are perpendicular to each other and also both the electric and magnetic fields are perpendicular to the direction of wave propagation i.e. if the wave is propagating in x-direction then electric field can be in z-direction and magnetic field can be in y-direction since all the three axes are perpendicular to each other.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
