As a form of energy, light has specific properties such as color and brightness. Some properties can only be seen with special tools. Think about properties of light and how color in white light can be investigated.
Which statements are true about light properties and how color in white light can be investigated?
A. White light can be separated using any glass object.

B. Light travels in a straight line until it strikes an object. When white light is separated by a prism, the colors appear in a random order.

C. The way light reacts when it strikes an object depends on the properties of that object. When a single-colored light passes through a prism, it becomes white.

D. As white light passes through a prism , it bends and separates into different colors

D. As white light passes through a prism , it bends and separates into different colors

Explanation:

When light enters a prism, it experiences a phenomenon called 'refraction'.

Refraction occurs when light crosses the interface between two mediums with different optical density; when this happens, the light bends and also changes speed.

The angle at which the ray of light is refracted into the second medium depends on the optical density of the two mediums, but also on the wavelength of the light.

In particular, longer wavelengths (red color) are refracted the least, while shorter wavelengths (violet color) are refracted the most.

As a result, when white light (consisting of all the colors of visible light) enters into a prism, they different wavelengths are separated: therefore, white light separates into different colors.

So, the correct answer is

D. As white light passes through a prism , it bends and separates into different colors

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
