2 part hw question: A. Explain the difference between a meteor, a micrometeor, a meteoroid and a meteorite. B. Describe how energy generated within the Sun reaches Earth. Solution A Meteorite: Meteorites are solid pieces of debris from an object in the universe Ex: comet, asteroid or meteoroid Meteoroid: Meteoroids are nothing but meteorite and their sizes will considerably smaller than an asteroid and considerably larger than an atom Micro meteoroid: It is meteorite and its size will be less than the gram. And these particles can reach the earth easily. Meteor: When the meteorites enters the atmosphere, various factors like friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate that energy. It then becomes like a shooting falling star and is called as meteor. B The energy generated in the sun travels in the space in the form of electromagnetic (EM) wave form. This energy has continuous energy spectrum. In this form the energy generated in the sun reaches the earth. In between earth and sun large vacuum will be there but EM wave can travel through the vacuum so up to earth atmosphere there will not be loss in the wave energy. But after reaching the earth atmosphere, some of the wave energy as a function of wavelength (frequency) will be absorbed and some will be scattered. And the remaining EM energy reaches the earth..

1. 2 part hw question:
A. Explain the difference between a meteor, a micrometeor, a meteoroid and a meteorite.
B. Describe how energy generated within the Sun reaches Earth.
Solution
A
Meteorite: Meteorites are solid pieces of debris from an object in the universe
Ex: comet, asteroid or meteoroid
Meteoroid: Meteoroids are nothing but meteorite and their sizes will considerably smaller than
an asteroid and considerably larger than an atom
Micro meteoroid: It is meteorite and its size will be less than the gram. And these particles can
reach the earth easily.
Meteor: When the meteorites enters the atmosphere, various factors like friction, pressure, and
chemical interactions with the atmospheric gases cause it to heat up and radiate that energy. It
then becomes like a shooting falling star and is called as meteor.
B
The energy generated in the sun travels in the space in the form of electromagnetic (EM) wave
form. This energy has continuous energy spectrum. In this form the energy generated in the sun
reaches the earth. In between earth and sun large vacuum will be there but EM wave can travel
through the vacuum so up to earth atmosphere there will not be loss in the wave energy. But after
reaching the earth atmosphere, some of the wave energy as a function of wavelength (frequency)
will be absorbed and some will be scattered. And the remaining EM energy reaches the earth.
