Physics Flashcards
1
Q
Thin lens equation
A
2
Q
Ohm’s Law
A
V=IR (v=voltage, I=current, R=resistance)
3
Q
index of refraction of a medium
A
speed of light in a vacuum/speed of light in a medium
4
Q
Electromagnetic radiation- proportionality
A
Energy of EM radiation is proportional to # photons (b/c the represent energy)
intensity- (energy/time)
5
Q
Atmospheric Pressure
A
760mmHG=1 atm=1 torr=101 kPa
6
Q
Power & Work
A
P=W/Time
7
Q
Alpha Decay
A
Loss of He2+ (when thinking about the type of decay, take the original molecule and “subtract” the same mass # and atomic # as He 2+)
8
Q
Beta negative decay
A
Beta Negative turns Neutron to Proton
9
Q
Beta positive Decay
A
Beta Positive Proton becomes Neutron
10
Q
Gamma emission
A
gamma rays are emitted from a molecule to remove energy & emits photon
