A simple diffraction device would show that white light contains a mixture of light of other wavelengths. If you want to see it yourself, you could buy a pair of basic diffraction glasses, or a similar instrument, for under $10.
Take a glass prism. Allow a narrow beam of sunlight through a small hole in the window of a dark room to fall on one face of the prism. Let the light coming out of the other face of the prism fall on a white sheet of a paper. We can observe seven colors on the paper because sunlight while passing through a prism splits into seven colors. So this activity proves that sunlight consists of seven colors

Using a prism
With a lense called a prism
White light is a mixture of colored light, and that each color is refracted to a different extent. The different colors correspond to light with different wavelengths, and are refracted to different degrees. This separation of colors is known as dispersion. Which causes the seperation of white light into seven colours Red, Orange, Yellow, Green, Blue, Indigo and Violet.
A prism will split light into its component colors. If a colored light is used, there will be less colors in the split light. A beam from a red light for instance will have very little blue or green light in it so you will not get the full spectrum from the prism.
White (sun) light contains different colors of lights, when passing through a prism. Plants rely on specific colors of lights to conduct photosynthesis. Since white light contains all the necessary colors of light for photosynthesis it is the most preferred light. Inquiry into Life Laboratory Manual Twelfth Edition Sylvia S.

white light contains all of the colors of the rainbow, so if all of the rainbow's colors shown collectively at one point, the light would be white light (like the sun's light).
When white light(composite light) consisting of various colors is passed through a prism, light of different colors will be deviated through different angles. Since the deviation is related to refractive index and refractive index to the color of light the deviation produced for different colors are different for same prism.That is the refractive indices are different for the various colors and this difference in the refractive indices is responsible for dispersion.

No. White light is a mixture of different colors.
Yes, white light is a mixture of many different colors.
White light is a mixture of different colors; so there are different frequencies.
Most light is a mixture of colors of the spectrum.* White light is composed of all colors. The different wavelengths of light are refracted at different angles, which separates them out into the constituent colors of the original light source. *Laser light is monochromatic.
White light contains all the colors. The different colors of light are at different frequencies. On the high frequency end you have violet and on the low end you have red.
The frequency of the EM wave determines the amount of energy it contains. Therefore, different colors of light have different frequencies and amount of energy.
White light is a mixture of different colors. A red object (for example) would reflect a greater percentage of red light, and a lesser percentage of other colors, thus making the light that you see redder.
White light contains lights of all frequences within it. So yes, white light is a mixture of all colours of light.
The index of refraction varies for different colors of light (i.e., for different wavelengths or frequencies), therefore, a source of white light, like rays from the Sun, can get separated into their components. White light isn't "pure" (monochromatic) light - it is really a mixture of many different colors.
This applies not only to opaque objects. The basic idea is that white light is a mixture of different colors, and objects tend to reflect the different colors - the components of white light - in different proportions. For example, an object that reflects most of the red light but not much of the other colors will look red.
