In infinite number, technically. The wavelengths of visible light have a lower boundary of around 380nm to a highest one of 750nm. But it's impossible to really say how 'many' wavelengths are in between that. You'd have some of the light at 380.1nm, then some at 380.01nm, then some at 380.001nm, etc.

What happens when white light is passed through a prism?
The white light gets split into its different wavelengths which we see as different colours. The different wavelengths get refracted at slightly different angles, and we see a rainbow effect.
The termrefraction means what in terms rainbows?
Water droplets refract different wavelengths of visible light differently. Blue wavelengths are less "bent" than red wavelengths, so the blue portion of the rainbow is towards the inside edge of the rainbow.
Do you see the wavelengths that are reflected or absorbed by matter?
We see wavelengths that are reflected off of matter.
Is a rainbow a transverse or compression wave?
A rainbow is made of different wavelengths (different colors) of light waves, and light waves are usually considered transverse waves.
What is visible lights?
Visible light includes all the colors of the rainbow. The different colors are the result of different wavelengths.

Why does a rainbow show colors from reds to violet?
There's a broad band of wavelengths of light coming from a rainbow. They range from wavelengths that are too short for your eyes to detect, all the way to wavelengths that are too long for your eyes to detect. Within that band of wavelengths is the total band that your eyes can detect, and you see them as a spread out display of all the colors that your eyes and brain can work together to perceive.

Water droplets refract different wavelengths of visible light differently. Blue wavelengths are less "bent" than red wavelengths, so the blue portion of the rainbow is towards the inside edge of the rainbow.
What color has the longest wave lenght?
The longest visible wavelengths are thoseat the red end of the spectrum (rainbow).
What happens when rain refracts sunlight and separates it into its component wavelengths?
Rainbow
Why is a rainbow considered to be an example of a continuous spectrum?
Continous spectra is the rainbow effect that you see when white light passes through a prism. It includes all of the visible light wavelengths, from about 380 nm to 780 or so.
Why rainbow have colors?
A water droplet in the air acts as a prism. It bends light into its component colour wavelengths which your eye sees as a rainbow.
When you see a rainbow in the sky or in the mist of a waterfall you are seeing all the wavelengths of visible light Which process separates the different components of the visible light spectrum so?
refraction
Do you see the wavelengths that are reflected or absorbed by matter?
We see wavelengths that are reflected off of matter.
Why does the rainbow arranged in roygbiv?
That's the sequence of the colors of light in order from longest to shortest wavelengths.
How and Why are colors dispersed in optics in a rainbow How do raindrops act as prisms Role of reflection and refraction in formation of rainbow?
The sun is all the different wavelengths of light. When all these lights hit water, the change in the speed of the light causes the light to defract away from one another, so you see th rainbow effect
