Answer 1

Answer:

1)Name the three components of sunlight in order of decreasing wavelength .

(2)Which one of them is observed by the upper layers of the atmosphere

Explanation:

1.Ordinarily, sunlight is broken down into three major components: (1) visible light, with wavelengths between 0.4 and 0.8 micrometre, (2) ultraviolet light, with wavelengths shorter than 0.4 micrometre, and (3) infrared radiation, with wavelengths longer than 0.8 micrometre.

2.The thermosphere is often considered the "hot layer" because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24).

Answer 2

Sunlight is broadly classified into three spectrums - ultraviolet light, visible light and infrared light.

UV rays are blocked by upper layers of atmosphere.

Explanation:

• Sunlight reaches from the sun to earth in around 8.2 seconds.

• Sunlight has different spectrums of electromagnetic rays that reaches earth along with light.

• The spectrums are namely Ultraviolet light, Visible light and Infrared light.

• The ultraviolet light is the light rays whose wavelength is below the blue light, i.e below 0.4 micrometer.

• The visible light is the light seen by us with bare eyes.

• Its wavelength ranges from 0.4 micrometer to 0.8 micrometer.

• The infrared light has wavelength more than red light of visible spectrum.

• Its wavelength is more than 0.8 micrometer.

• Ozonosphere is one of the top layers of atmosphere.

• It has ozone gas which blocks the entry of ultra violet rays on Earth's surface.
