Whate type of wave is made up of a sine wave plus all of its odd harmonics?

Answers

Answer 1

Answer: If the phase and magnitude of each harmonic is just right, you can make a 'square wave' with those.

Which kind of waves are sound vibrations made of?transverse
circular
longitudinal
latitudinal

Answers

The answer is longitudinal. There are two types of waves: transverse and longitudinal. Transverse waves are those whose vibrations are perpendicular to the direction of the wave. Longitudinal or compression waves are those whose vibrations are in the same direction as the wave. Sound is caused by the compression of vibrations of molecules.

Answer:

longitudinal

If you wanted to increase the voltage, which would you use?a. generator
b. step-up transformer
c. step-down transformer
d. motor
e. detector

Answers

The correct answer of the question is : B) Step-up transformer.

EXPLANATION :

Before coming into any conclusion, first we have to understand the step-up and step-down transformer.

The step-up transformer is the transformer whose transformer ratio is greater than one. It means it will increase the voltage of the source or decrease its current.

On the other hand, the transformer ratio of step-down transformer is less than one. Hence, it will decrease the higher voltage to lower voltage or increase the lower current into higher current of the given source.

As per the question, we want to increase the voltage of the source.

Hence, we have to use step-up transformer.

b) step-up transformer

What type of wave is a microwave

Answers

Answer: The correct answer is electromagnetic wave.

Explanation:

In the electromagnetic wave, both magnetic field and electric field are perpendiculars each other to the direction of the motion of the wave.

Electromagnetic spectrum is the range of frequencies of electromagnetic radiations.

Microwave is an electromagnetic wave. It falls in the range of electromagnetic spectrum between radio and infrared rays. It is a high bandwidth communication. It is used in RADAR and for heating purpose in microwave oven. Its frequency range lies between 300 MHz and 300 GHz.

Therefore, microwave is the type of electromagnetic wave.

it would be a electromagnetic wave
