Optics review questions

Optics questions for review

Exam 2 on 11/12/18

1.  Review the concept of reflection, particularly the law of reflection.  Draw what happens when a light ray hits a mirror at various angles.

2.  Review the concept of refraction:  what it is, what causes it, what happens during it, under what circumstances does light bend, etc.  Draw what happens when a light ray hits a block of transparent plastic at various angles.  

3.  Show how to calculate the wavelength of WTMD's signal (89.7 MHz).

4.  This problem has to do with the Doppler Effect.
a.    Write out a sentence that explains the Doppler Effect.


b.    If an ambulance is driving toward you with its siren on (frequency equals 1000 Hz), what would be true about the frequency YOU hear (compared to the one that is emitted by the ambulance)?

c.    If an ambulance has driven past you with its siren on (frequency still equals 1000 Hz), what would be true about the frequency YOU hear (compared to the one that is emitted by the ambulance)?

d.    What is true about the frequency the ambulance driver hears?

e.    What is the difference between a red shift and a blue shift?



5.  Some questions related to how light is affected by optics.

How things wave Introduction to WAVES. So - Waves.....   We spoke about energy.  Energy can, as it turns out, travel in waves.  In fact, you can think of a wave as a traveling disturbance, capable of carrying energy with it.  For example, light "waves" can have energy - like solar energy.  Ocean waves can certainly carry energy.   There are several wave characteristics (applicable to most conventional waves) that are useful to know: amplitude  - the "height" of the wave, from equilibrium (or direction axis of travel) to maximum position above or below crest  - peak (or highest point) of a wave trough  - valley (or lowest point) of a wave wavelength (lambda - see picture 2 above)  - the length of a complete wave, measured from crest to crest or trough to trough (or distance between any two points that are in phase - see picture 2 above).  Measured in meters (or any units of length). frequency (f...

The sound of music

Tonight we will chat about the most well-known of mechanical waves:  sound. Sound is a mechanical wave, meaning that it REQUIRES a medium through which to travel.  Whereas light (or other EM waves) can travel anywhere (more or less), and travel fastest (at the speed of light) through a vacuum, sound is restricted greatly.  It can only travel through a medium, which itself carries the vibrations that are sound waves. The same characteristics previously discussed still apply:  frequency, wavelength, speed, amplitude, crest, trough.  However, sound itself is a longitudinal wave (jiggling "back and forth") rather than a transverse wave (like EM waves, which vibrate "up and down"). Wave definitions to recall Frequency (f) - number of waves per second (measured in hertz, or Hz).  For sound, frequency refers to pitch.  Some frequencies are defined as notes Wavelength ( 𝝺 ) - the length of the wave, from crest to crest, etc. (in m). The...

Kahoot questions from this evening - answers are below

1.   1.  Which particle is fundamental (unable to be broken up further)? Proton Electron Neutron All are fundamental 2.   2.  When statically charging an object, you are actually moving: Proton Neutron Electron Quark 3.   3.  What is the voltage of a standard D-cell battery? 1 V 2 V 9 V 1.5 V 4.   4.  Two light bulbs are in series. One is unscrewed. What happens to the other one? It also goes It gets brighther Nothing happens It blinks on and off 5.   5.  What is true about the Earth's magnetic North Pole? It is the same as the Earth’s geographic North pole. It is at the equator. It is actually a south pole. None of these are true. 6.   6.  This symbol, a plain rectangle, is the electrical representation of a: Resistor Wire Battery Capacitor 7.   7.  Two light bulbs are in parallel. If the top bulb is unscrewed, what happens to...
