The laboratory equipment to be used are the balance and a beaker whose size depends on the volume of the unknown).
First, the mass of the empty container then pour in all the liquid and read off the mass.
Subtract the mass of the empty container from the total mass.
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.
The correct answer would be, false.
