Electromagnetic energy (of which light is one type) with a
frequency of 1,000,000,000,000,000 Hertz, or 1015 Hertz or 1
petaHertz has a wavelength of **2.995 x 10-5 cm**. That puts the
radiation at the top edge of the visible spectrum or in the near
ultraviolet region. Better get out your sunblock just in case.
You'll find links below to a "converter" to change wavelength to
frequency and vice versa, and also to an abbreviated chart of the
electromagnetic spectrum so you can see where stuff is on it. Now
*you* can post answers to questions like this one!

### Why do frequency of em waves increase as wavelength increases?

Frequency = Speed of Light / Wavelength.
As you can see from this formula, when the wavelength increases the
frequency decreases.
For example, we will say that the standard wavelength is 5m.
F = 3.0 x 108 / 5
= 60,000,000 hertz
Say if we increased the wavelength to 6m:
F = 3.0 x 108 / 6
= 50,000,000 hertz
As you can see, if we increase the wavelength, the frequency
decreases.
If we decreased the wavelength to 4m:
F = 3.0 x 108 / 4
= 75,000,000 hertz
As you can see, if we decrease the wavelength, the frequency
decreases.

### What is frequency of blue light with wavelength of 500 nanometers?

~599.584916 terahertz
Basic formula
Frequency (In Hertz) = 300,000,000 ÷ Wavelength (In meters)
300,000,000 look familiar? Speed of Light in meters per
second
500 nanometer = .5 micrometers = 5.0e-7 meter
Frequency (In Hertz) = 300,000,000 ÷ 5.0e-7 meter
599.584916 terahertz (1e+12 hertz) = (.5) wavelength in
micrometers

### What is the frequency of light?

it depends on the wavelength
========================
The frequency of any electromagnetic signal ... in fact the
frequency of any wave ... is
(speed of the wave)/(wavelength) .
For light, that's 300,000,000/(wavelength in meters) , and the
answer is in Hertz.
The lowest frequency of light that your eye can detect is
around 7.5 x 1014 Hz.
That's 750,000,000,000,000 Hz ... 750,000 Gigahertz ! (for 400
nm wavelength)

### What is the speed of the solar signal in water with a frequency of1000 hertz and wavelength of 1.5?

I assume that a "solar signal" means light.
Light moves at approximately 262 million meters per second in
water, regardless of the frequency or wavelength of the light.
Also, if light has a frequency of 1000 Hz, then it has a
wavelength of 300 kilometers. The speed of light, c, is equal to
the product of the frequency and the wavelength. In other words,
c=f*w
