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 type of EM waves do we see in the rainbow?
We see visible light waves in the rainbow, which are a portion of the electromagnetic spectrum. These waves are perceived by our eyes as various colors due to their different wavelengths.
What is the part of the em spectrum that we can see?
The part of the electromagnetic spectrum that we can see is visible light. Visible light consists of the colors of the rainbow, ranging from violet at shorter wavelengths to red at longer wavelengths. This portion of the spectrum is detected by our eyes and is responsible for our sense of sight.
Why do you see a rainbow after a rainstorm?
After a rainstorm, sunlight is refracted and reflected by raindrops in the air, creating a spectrum of colors called a rainbow. Each raindrop acts like a prism, dispersing the sunlight into its different wavelengths, which form the colors of the rainbow.
What wavelength of light do human see?
Humans are able to see visible light, which has wavelengths ranging from approximately 400 to 700 nanometers. This corresponds to the colors of the rainbow - violet, blue, green, yellow, orange, and red. Beyond these wavelengths, such as ultraviolet and infrared light, humans cannot see without special equipment.
Why can white light refract to show all the colours of the rainbow?
White light is composed of a spectrum of colors with different wavelengths. When white light enters a medium like glass or water, each color refracts at a slightly different angle due to their different wavelengths. This separation of colors produces the spectrum of colors we see in a rainbow.
What type of EM waves do we see in the rainbow?
We see visible light waves in the rainbow, which are a portion of the electromagnetic spectrum. These waves are perceived by our eyes as various colors due to their different wavelengths.
What is happens when white passing 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.
Does the invisible spectrum contain all colors of the rainbow?
Yes, the invisible spectrum includes wavelengths beyond what our eyes can detect, such as ultraviolet and infrared light. These wavelengths do not correspond to the colors of the rainbow that we can see with our eyes.
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.
Why is there no pink in the rainbow?
Pink is not included in the typical rainbow because it is a combination of red and violet light, which are at opposite ends of the rainbow spectrum. When light is refracted and dispersed in raindrops, pink is not seen due to the specific wavelengths of light that create the colors of the rainbow.
What is the part of the em spectrum that we can see?
The part of the electromagnetic spectrum that we can see is visible light. Visible light consists of the colors of the rainbow, ranging from violet at shorter wavelengths to red at longer wavelengths. This portion of the spectrum is detected by our eyes and is responsible for our sense of sight.
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 isn't there white color in rainbow?
White light is actually a combination of all the colors of the rainbow. When white light passes through a prism, it separates into the different colors of the spectrum due to their different wavelengths. The colors we see in a rainbow are a result of this separation of white light.
What happens when rain refracts sunlight and separates it into its component wavelengths?
Rainbow
What causes the relative width of colors on a rainbow?
The relative width of colors on a rainbow is caused by the different wavelengths of light being refracted and dispersed by water droplets in the atmosphere. Shorter wavelengths (like blue and violet) are refracted more than longer wavelengths (like red), leading to the distinct width of colors seen in a rainbow.
