about £200-£400 is my guess
A lens with lower aperture would be great, something less than F2.8 would give you more light to the subject, ISO should be around 400-1600 ( mid range- high range camera) , keep the shutter speed around 1/200-1/20, if you have tripod you can go for lower shutter speed.
The content of the picture and what "Quality" level you are using affects how many pictures a memory card will hold. A 2 GB card in a 7.2 MP camera will hold something like 800 pictures on medium quality and 400 pictures on high quality.
I have a Canon Ixus 400 and have been using a 1GB Integral memory card on it for years - works absolutely fine!
The wave length of visible light ranges from 400 nm to 700 nm
The wave frequency for 400 nanometers is approximately 750 terahertz (THz). This can be calculated using the formula: frequency = speed of light / wavelength.
"Wave speed" is meaningless. Do you mean wavelength? That's roughly 400-700 nm.
Just ONE property, the wavelength of the light. The colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end.
Light wave is an electromagnetic wave, so light waves are a kind of wave. I don't understand what you mean by what waves have the most light waves. It's not possible to emit a combination of different kinds of waves (such mechanical, EM wave, sound wave) from a single source.
The wavelength of the electromagnetic wave determines whether it is visible light or infrared radiation. Visible light has shorter wavelengths than infrared radiation. The range of wavelengths for visible light is approximately 400-700 nanometers, while infrared radiation has longer wavelengths ranging from 700 nanometers to 1 millimeter.

Visible light waves are electromagnetic waves, within a certain range of frequencies. The wavelength of visible light is between about 400 and 700 nm. Some of the characteristics of electromagnetic waves include:* Carried by particles called photons* The wave is a wave in the electric and magnetic fields* In a vacuum, this wave (and the photons) propagates at the so-called speed of light, which is about 300 million meters/second.

The laser light is the type of light that only has one wavelength in its phase. Coherent light is light that has a single frequency and wavelength, and can be described with a single wave equation.
Light exhibits the qualities of both a particle and a wave. Wave-particle duality is a fundamental concept of quantum mechanics, and it is used to assist in explaining the nature of, in this case, light. Light does, indeed, exhibit both the qualities of a particle and those of a wave. And why is light a wave? Because it is. It is a wave because being a wave is an integral part of its fundamental nature. We cannot separate the wave characteristic from light and still have light. Light behaves like a wave, and that is why it is a wave. Perhaps it might be more helpful to say light behaves as it does, and "wave" is the word we use to describe its behavior. Perhaps that perspective, the view that light does its thing and we call what it does a wave, will make it easier to understand and accept that light is a wave.

Human vision is limited to the visible spectrum of light, which ranges from about 400 to 700 nanometers. Wavelengths shorter than 400 nm (such as ultraviolet light) and longer than 700 nm (such as infrared light) are not visible to the human eye.
