Explanation

Light is a form of energy.

Light is actually energy made of small particles called photons.

Explanation

The renewable energy sources are:

• Water energy
• Wind energy
• Tidal energy
• Hydroelectric
• Ocean energy
• Geothermal energy
• Biomass
• Biogas

The non-renewable energy sources are:

• Fossil fuels or Hydrocarbon fuel (Oil, Natural gas, Coal)
• Nuclear energy

Explanation

• Light travels in a straight line.
• It is also known as a rectilinear path.
• It in a homogeneous medium like air or vacuum.

Explanation

A scalar quantity has only magnitude and no direction.

Examples include mass, time, temperature, and speed.

Explanation

Explanation

• The purest source of natural water is Rainwater. The rainwater at once comes from the condensation of water within the presence of the solar. The water evaporates from the lakes, rivers and seas. all the impurities are eliminated in the course of the vaporization procedure, and then waterfalls immediately into the earth inside the form of rain.
• In chemistry, pure water refers to an natural water solution that is freed from any dissolved salts or gases. easy consuming water, then again, includes lines of minerals like salt and magnesium, as well as carbonates and dissolved gases like oxygen, as required by way of the WHO.
• Rainwater is the purest herbal source of water. within the case of the sun, rainwater is immediately derived from vapour condensation. Ponds, lakes, and rivers evaporate their water. All pollutants are removed during the vaporization step, and water in the shape of rain falls immediately into the soil.
• As a end result, rain is considered the purest type of water.

Explanation

Sound wave is a mechanical  wave.

Explanation

Without sunlight, there would be no scattering of light by the Earth's atmosphere.

This means that no scattered light would reach our eyes, and the sky would appear black.

Explanation

Explanation

Solar and wind energy are renewable sources of energy, meaning they are sustainable and will not run out.

Solar energy is generated from the sun's rays.

Wind energy is generated from the wind.
