What is waving in an electromagnetic wave?

Physics
1 answer:
BARSIC [14]3 years ago
4 0

Answer:

The electric field and the magnetic field

Explanation:

An electromagnetic wave consists of oscillations of an electric field and a magnetic field, oscillating perpendicularly to each other. The oscillation of the two fields also occur on a plane which is perpendicular to the direction of the propagation of the wave itself (due to this feature, this kind of waves are called transverse waves).

One of the main difference between electromagnetic waves and other waves is that electromagnetic waves are the only one that can travel through a vacuum, since they do not need a medium to propagate (such as, for example, sound waves).

The speed of the electromagnetic waves is constant in vacuum and its value is called speed of light, equal to:

c=3.0\cdot 10^8 m/s

Andre heated several solid crystals of a substance called iodine, and the iodine changed directly to a gas. The iodine gas then
Strike441 [17]

The correct choice is

B. sublimation, then condensation

Sublimation is the name of the process where a solid directly converts into gas on heating. on heating solid crystals of iodine directly change into gas. hence this is sublimation.

condensation is the process where gas is converted into liquid on cooling.

here iodine gas is being converted into droplets on reducing the temperature. hence this is condensation.

Mars2501 [29]

Answer:

According to Newton's 2nd law

The force acting on a body produces acceleration in its direction which is directly propotional to the force but inversly propotinal to the mass of tbe body.

Explanation:

a = F/m

F = ma

Where( F) is force (m) is mass and (a) is acceleration.

Elodia [21]

Explanation :

A power amplifier is used to amplify electric signals i.e. to increase the low power signal to higher powers.

A PNP transistor is connected in a circuit so that the collector-base junction remains reverse biased and the emitter-base junction is forward biased.

This transistor can be used as a power amplifier because it gives a much larger output current. The gain of an amplifier shows the amount of amplification. It is the difference between the input and the output signals.
