Answer:
Sound and light are similar in that both are forms of energy that travel in waves.
Explanation:
They both have properties of wavelength, freqency and amplitude. ... Sound can only travel through a medium (substance) while light can travel through empty space. Sound is a form of mechanical energy caused by vibrations of matter.
Answer:
It involves observation
It involves experimentation
It is supported by evidence
Explanation:
Science can be described as a system of knowledge based on the understanding of the natural world. The subject of science requires the scientific method - a chronological series of steps that have to be followed while trying to understand events in the natural world. These steps are:
- <em>observation</em>
- <em>formulation of hypothesis</em>
- <em>testing of the hypothesis by experimentation</em>
- <em>conclusion based on available evidence from the experiment</em>
Hence, science involves <u>observation</u>, <u>experimentation</u>, and <u>it is supported by evidence</u>.
