# Which one of the following are examples of electromagnetic wave 2 points.

## Which one of the following is an example for an electromagnetic wave 2 point?

red light are examples of electromagnetic waves. The only electromagnetic waves that we can see are visible lights. The electromagnetic waves can travel through vacuums, which is empty space. But mechanical waves cannot.

## Which statement is true about the electromagnetic spectrum?

Expert Verified This statement tells you a fact about electromagnetic spectrum. The electromagnetic spectrum includes visible light as well as a variety of non-visible radiation.

Which statement correctly describes both sound and light waves?

Answer to Option C. Sound waves cannot travel through space but light waves can.

### Which statement about a wave produced by doorbell is true?

“It propagates as a result of compression and rarefactions” refers to the only statement in the question about the wave produced by a doorbell. Of all the choices, the correct answer is “B”, or the second option. I hope you find the answer helpful.

### What is the distance between two consecutive crests called?

The crest is the highest part of a wave’s surface, while the trough is its lowest. Wave height is the vertical distance between crest and trough. The wavelength is the horizontal distance between two adjacent or near-identical crests and troughs.

What is the distance between the two troughs?

Read:  How can I connect two networks together?

The wavelength is the distance between the two bottoms. Wavelength is the distance between two consecutive crests or valleys in a wave. The crest is the highest point on the wave, while the trough the lowest.

#### What is the distance between successive waves?

The wavelength is the distance between successive crestings or successive troughs. The period is the time between crossings of successive crests at a given point.

#### What is the frequency of a wave equal to?

Frequency is the frequency of periodic events per second. It’s measured in cycles/second. In this example, 1 cycle is equal to 2 seconds. The frequency is therefore 1 cycles/2 s=0.55 Hz.

What are waves created by?

Waves most often occur due to wind. Surface waves or wind-driven waves are caused by friction between wind and water. Wave crests are created when wind blows across the ocean’s surface or lake.

## What is referred as the number of waves produced in one second?

The frequency of a wave refers to the number of waves that are produced by a source every second. It also refers to the number of waves passing a given point every second. The hertz (Hz) is the unit of frequency.

## What is the period of a wave with a frequency of 200 Hz?

Since 200/s is in fractional form, you have to find its reciprocal form and multiply it to one which would give you 1 (one) second over 200. The value 0. would be obtained. 005 seconds as the wave period. This would give us a 0. 005 s.
