<span>The proportion of dissolved salts to pure water in the ocean is known as salinity. This is commonly measured in parts per thousand. For example, if the salinity of an ocean is 35 parts per thousand, or ppt, this means that in every kilogram, or 1000 grams, of ocean water, there are 35 grams of salt present. The higher the quantity of parts per thousand, the saltier the water, which also means the higher the salinity.</span>

Answer:
For any experiment we can say that light waves are the electromagnetic waves because they make up what is known as the electromagnetic spectrum.
Explanation:
- Light is the moving energy form that is made up of tiny particles known as photons.
- The light waves comprises of both magnetic and electric aspects hence known as electromagnetic.
- The process of propagation of light wave is : the fields vibrates perpendicularly in the same direction of propagation of the wave, and at 90 degree angle with each other.
- Similar to sound waves, light wave can interfere with each other.
