chapter 3

Question 1

What is the distance between successive wave crest and troughs

Answer 1

Wavelength

Question 2

Number of wavecrests that pass a given point per second hertz, he. Inversely proportional to the wavelength

Answer 2

Wave frequency

Question 3

What is the speed of electromagnetic radiation

Answer 3

300,000 KM/seconds 186,000 miles/seconds the speed of light

Question 4

At a constant temperature it absorbs all radiation it receives and emits all the Energy it absorbs.
Perfect absorbs And perfect emitter
Surfaces approximate these for certain wavelengths of radiation

Answer 4

Blackbody

Question 5

What is WI EN displacement law

Answer 5

Wavelength of most intense radiation emitted by a black body is inversely proportional to its absolute temperature

Question 6

The Suns cooler visible surface. Much Cooler than interior:

Answer 6

Photosphere

Question 7

What are sunspots

Answer 7

Cool areas on the sun surface accompanying bright area called faculae

Question 8

What is chromisphere?

Answer 8

Sons atmosphere of superheated gases mostly H and He.

Question 9

What solar corona?

Answer 9

The outermost portion of the suns atmosphere

Question 10

When the north pole is tilted towards the sun the northern hemisphere receives or solar radiation which two seasons is this

Answer 10

This is spring or summer in the northern hemisphere

Question 11

When the north pole is tilted away from the sun the northern hemisphere receives less solar radiation what seasons of this are this?

Answer 11

This is fall or winter in the northern hemisphere

Question 12

The way the sun tilts towards or away from the earth north pole is called what

Answer 12

Inclination of Earth axis

Question 13

What is the solar constant

Answer 13

Rate at which solar radiation falls on a surface located at the outer edge of the atmosphere oriented perpendicular to the incoming solar beam when earth is a mean distance from the sun

Question 14

Solar radiation passing to the earths atmosphere interacts with what

Answer 14

Gases and aerosols via scattering reflections and and abroaption

Question 15

So the radiation and the atmosphere: describe scattering

Answer 15

PArticles disperse solar radiation the scattering a blue violet light oxygen and nitrogen molecules this is why daytime sky is blue

Question 16

Solar radiation in the atmosphere: describe reflection

Answer 16

Takes place at the interface between two media when the radiation striking interface is redirected backscattered a fraction of incident radiation back scatter by airborne particles or reflected by is surface is a albedo of that surface

Question 17

What is an albedo

Answer 17

The reflection of energy scattered on earths surface is redirected to outerspace whistler visible energy is reflected from earth back into space

All surfaces have it not just earth

Question 18

Solar radiation in the atmosphere absorption

Answer 18

It’s radiation to heat energy

Question 19

What element has the highest albedo at the lowest solar altitude

Answer 19

Water global average oceanic albedo is 8%

Question 20

Electromagnetic radiation can be defined as what

Answer 20

It is a transmitted through space or materials as waves solar radiation both electric and magnetic properties

Question 21

What is the global solar radiation budget?

Answer 21

Earths surface principal recipient of solar heating and main source of heat for the atmosphere. Evident in critical profile of the troposphere.
