Base's physical characteristics:
1) Bitter in taste
2) Soapy feeling (in shampoo or body wash)
3) pH>7

Base's chemical characteristics:
1) BASW ( Base reacts with Acid to form Salt and Water)
2) Ability to turn moist red litmus paper blue due to its basic properties. (pH>7)
3) IMPORTANTLY is that it dissociate Into OH- ions or hydroxide ion when dissolved in water! (For alkali)

Alkali is SOLUBLE salt. Most bases are insoluble.

Sergeu [11.5K]

Answer:

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
