LIGHT
Page edited by William Harm

This page has a lot of information about light and the other forms of waves on the electromagnetic spectrum, what it is, and links where you can find more info. Where does light come from? Is all light visible? Is it all a wave or is it a particle? When is light absorbed and when does it bounce? Visible light waves are the only
electromagnetic waves we can see but there are a few other types of wavelengths we humans cannot see.

WHAT IS LIGHT?

This is a very helpful site explaining what light generally is such as what it is, how fast it goes, how it travels, and how it bends.
It also shows a few examples examples and animations of light well.
Accuracy: The information on the site is well accurate and up to date for the most part and there are no facts that contradict each other.
Readability and clarity: The site is clear on what it is trying to say. The information presented is presented well enough that even six or seven year olds can read and understand it.
Ease of Navigation: It is easy to find out more, there are other links to other pages on the site.

WHAT IS THE ELECTROMAGNETIC SPECTRUM?

This is a site that tells not only what the electromagnetic spectrum is but what the different wavelengths are even the visible light that we humans see.
Accuracy: The site looks accurate enough not only about what the electromagnetic spectrum is but also about the wavelengths and does show examples of each different wavelength and about the spectrum. There also seems to be nothing that contradicts each other on the site.
Readability and Clarity: The audience is more for middle school and up people. A lot of people can read it easily. The information is presented formally but not in an essay or slide show format.
Ease of Navigation: It is pretty easy to find out more since there is more than one page on the site about this.

This site answers a few general questions when it comes to visible light such as what it is. It also explains why we can see visible light as well as true and false color images from satellites and gives examples.
Accuracy: The site does explain visible light and how we see it and nothing condradicts each other.
Readability and Clarity: The site does explain what it is trying to say. The information that is presented in a way that it might be for high school students.
Ease of Navigation: It is easy to find out more on the other types of wavelengths. There are more pages to the site from the homepage.

This site explains what infrared waves of the electromagnetic spectrum are and the forms the waves come in.
Accuracy: The site is accurate on what infrared waves are and the different forms of infrared waves such as thermal and heat radiation. The site also explains how humans experience and produce infrared waves every second of every day plus nothing contradicts each other.
Readability and Clarity: This site is not really meant for young kids but more for high school students and older. It is well easy to read for those that actually take the time to read it.
Ease of Navigation: It is easy to find out more. There are other links to other forms of waves on the site.

This site explains the fantastic and dangerous world of X-rays and how they are produced. The site also includes a bit of a history lesson on how the wavelength is or was first discovered.
Accuracy: The information is accurate and up to date for the most part and nothing contradicts each other.
Readability and Clarity: It is really straight forward so the audience is not really middle school kids but rather college type people and older. The site is easy to read.
Ease of Navigation: It is not really easy to find out more unless someone wants to find out about the other wavelengths.

This site explains radio waves, what are they, what are they used for, and a lot of other things.
Accuracy: The information is up to date and nothing contracting each other.
Readability and Clarity: The audience like pretty much always is high school students and older.
Ease of Navigation: There are other links but those are for other electromagnetic wavelengths so there is not much more about radio waves linked to this site
