Electromagnetic spectrum question???????

Question

Put the following regions of the electromagnetic spectrum in order of increasing energy: gamma rays, infared, tv waves, ultra-violet waves, visible, radio waves, microwaves

This is the order
Radio waves, microwave, infrared, visible, ultraviolet, x-ray, and gamma ray radiation.

But I do not know where TV rays fit in the energy order?

correction- TV waves

Answer 1

TV waves are radio waves in the VHF and/or UHF range.

AM radio has frequencies between 540 kHz to 1690 kHz (approximately - I can't remember the exact frequencies).

TV channels 2-6 run from 54 MHz to 88 MHz.

FM radio runs from 88 MHz to 108 MHz.

TV channels 7-13 run from 174 MHz to 216 MHz

UHF channels run from 470 MHz to 806 MHz.

That makes it hard to distinguish been commercial radio frequencies and commercial television frequencies. In addition, there's a lot of military, government, and civil radio frequencies that fit into available slots, as well. Usually, TV is just included among the radio waves, since the only difference is that the information on TV's radio waves includes picture information in addition to audio information.

In fact, microwaves could also be considered just a higher frequency of radio/TV waves - especially given the advent of satellite TV where TV signals are transmitted on microwave frequencies.

Analog TV signals can be received in the C-band of microwave frequencies with any satellite dish and receiver (unless the signal's encrypted). Today, digital TV signals multiplexed together (a bunch of TV stations sharing the same frequency) in the K-band (higher than the C-band) of the microwave frequencies are popular with satellite TV.

In other words, giving TV a specific range is kind of obsolete. If it has any meaning, it's only because old traditions die hard.

Answer 2

TV Rays fit right in with radio waves.

The spectrum for common TV signals in both cable TV and broadcast TV is between 5 and 700 Mhz depending on the channel.

Satellite broadcast TV varies though. There is your regular Satellite broadcast spectrum from 900Mhz-1200Mhz then you get into the KU band and I get a little fuzzy on the frequencies. I think it goes up to 2.4Ghz.

So basically TV can cross from Radio waves to microwaves depending on what TV you are talking about.

I might be off a little on the frequencies because I'm not looking at my broaadcast frequencies chart right now, but should be fairly close.

Answer 3

Frequency is directly related to energy. Higher frequencies means higher energy.

TV wave frequencies mixed in with the radio waves.

AM broadcast is 0.54 -1.6 MHz -- low frequency.
TV waves for the low channels (2-6) are 54-88 MHz
FM broadcast is 88-108 MHz
TV for channels 7-13 are 174-216 MHz
TV channels 14-83 are 470-885 MHz

All of these are below microwaves, which are often considered to begin at about 1000 MHz (1 GHz).

Answer 4

As a couple of other answerers already pointed out, the frequencies for TV are intermingled with radio frequencies, which makes the question not entirely fair. If this is for an assignment, it might be worth talking to the tacher about it.

But to put them in order by energy, I'd go with radio first, then TV. Energy output increases with frequency, and if you consider the best-known TV and radio frequencies, TV is going to sit a little higher on the spectrum than radio.

Answer 5

TV waves are larger than radio. The energy is measured in their height. The ones that can go through the body are the gamma, Xray, but microwave can injure as can infrared and ultraviolet.

Answer 6

Between radio and microwaves
