Explanation

Solar energy is radiated from the sun in the form of electromagnetic waves of shorter wavelength of 0.2 to 0.4 micrometers.

Out of all the solar energy radiations reaching the earth's atmosphere,

8% is ultraviolet radiation,

40% is visible range light 

46% is by infrared radiation.

Explanation

An analog signal is a voltage, current, or physical quantity that continuously and infinitely varies in accordance with some time-varying parameter.

For example, radio waves, television waves, or sound waves are all examples of analog signals.

Explanation

The process in which the change of vapor or gas into liquid is known as condensation

Some examples of water condensation:

• Morning dew on the grass.
• Water droplets on the outer surface of cold drink bottle.
• Foggy car windows

Additional information:

The process of change of state from solid to liquid is called melting

Evaporation is the conversion of liquid into its vapor, below the boiling point of liquid.

Explanation

A scientific theory is a well-substantiated explanation of some aspect of the natural world

Both scientific laws and scientific theories are typically well-supported by observations and/or experimental evidence.

Explanation

A volcanic eruption is the release of heat energy by Earth's power. this process is called convection because

Convection is the movement of particles through a substance, transporting their heat energy from hotter areas to cooler areas.

Additional Information:

Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules.

Radiation is energy that comes from a source and travels through space at the speed of light.

Explanation

Fission is much easier to achieve than fusion although fission produces long-term radioactive by-products that are not created with fusion.

the suns are fusion reactors. 

Explanation

All of these electromagnetic waves (whether radio, visible, or gamma) travel at the same speed.

They all travel at the 'speed of light' through a vacuum, that is at 3 × 10 8 m s-1

Explanation

Sunspots are dark areas in the Sun's photosphere, which are cooler than their surroundings

The Sunspots on the Sun's Surface with a periodicity of 11 years.

They consist of a central darker region, known as the umbra,

and a surrounding region, known as the penumbra.

Additional Information:

Bright spots on the surface of the sun are called Plages

Explanation

• The stratosphere prevents UV rays from surface of the Earth
  
• 90% of the ozone in the atmosphere is occupied by the Stratosphere.
• Ozone molecules are constantly formed and destroyed in the stratosphere

Additional Information

Ozone is a molecule that contains three oxygen atoms

The atmosphere can be divided into five layers:

1. Troposphere (all weather occurs within this layer)
2. Stratosphere (ozone layer absorbs UV rays)
3. Mesosphere (coldest layer of the atmosphere)
4. Thermosphere (radiowaves transmitted from the Earth and reflected by this layer)
5. Exosphere (molecules and atoms escape)

Explanation

The James Webb Telescope launched in orbits the Sun 1.5 million kilometers (1 million miles) away from the Earth

JWST was launched on 25 Dec 2021 on Ariane Flight VA256

It is a successor to the Hubble Space Telescope.

JWST is a space telescope developed by NASA

It is the world's largest and most powerful space telescope

The telescope is named after James E. Webb, who was the administrator of NASA from 1916 to 1968

Additional Information:

The Hubble Space Telescope was launched into low Earth orbit in 1990

The Spitzer Space Telescope is an infrared telescope launched in 2003 and retired on 30 January 2020
