Download Can you write numbers in scientific notation

Exam 2 Review
This “review sheet” has a list of questions that you can ask yourself to get a feel for
your own comfort level on the different topics that we’ve covered in class.
Exam 1 Carry-over:
Are you able to write numbers in scientific notation and read/interpret numbers presented
in scientific notation?
Can you use scientific notation to make calculations?
Do you know how to use your calculator properly?
Can you convert measurements in the metric system to other units within the metric
system? How about converting between the metric and British systems?
Matter/Light Properties
Can you describe the structure of an atom? Do you know what makes one element
different from another?
What is an isotope? What is a molecule?
Do you understand how the concept of temperature is related to the motion of
atoms/molecules? Do you understand how changing the temperature of a substance will
change the excitation state (ground, excited, ionized) of atoms as well as the state of
matter?
Can you define the wave properties of light (wavelength, frequency, speed of light)?
Do you understand how light can be described as a particle (photon)?
Can you make the following calculations if you are given the equations?
- energy of an individual photon
- luminosity of a star
- the wavelength of light that is emitted by a star in the greatest amount (λpeak)
Do you understand the properties of light that are given by Maxwell’s Equations?
Do you know the basic principles of the reflection and refraction of light?
Do you know how to compare the different parts of the EM spectrum with regards to
wavelength, frequency, and energy?
Do you know how light and matter interacts to form an absorption spectrum?
Star Properties:
Are you familiar with how astronomers use solar units as a way of describing physical
qualities of other stars?
Do you know the surface temperature, total lifespan, and general composition of the Sun?
How is the process of stellar parallax used to determine the distance to a star?
Do you understand how the brightness of a star depends on the star’s luminosity and the
distance an observer is away from the star?
Are you familiar with how the magnitude system is used to rank stars according to
brightness (apparent magnitude) and luminosity (absolute magnitude)? Can you use the
magnitude system to obtain the relative distances to stars?
Do you know how the order of spectral classes is arranged? Can you tell a star’s relative
temperature, color, and luminosity based on its designated spectral classification?
Can you use the Doppler Equation to determine how fast a star is traveling in space? Do
you know how to tell whether a star is moving in a direction toward or away from the
Earth?
