OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

INTRODUCTION S UPPLEMENTARY UNITS
2 rad
• The International System of Units (SI) is a • Radian and steradian are often listed as
modern version of the metric system supplementary units; the current international 3 rad
agreement puts these two dimensionless units
• As a result of a long series of international
discussions, on the 14th of October, 1960, into the derived unit category π rad 1 rad
the Eleventh General Conference on Weights • The radian (rad) is the plane angle formed π = 3.1416
and Measures agreed to adopt the symbol SI between 2 radii of a circle subtended by an arc
(Le Systéme International d’Unités) to whose length is equal to radius; there are 2p
describe system of measurements consisting rad in a circle
THE RADIAN (rad)
of seven basic units, two supplementary • The steradian (sr) is the solid angle at the
units, and numerous derived units

• These units appear on this chart along with the sphere’s surface which is equal to the = 1 r2
their definitions square of its radius; there are 4p sr in a sphere solid angle
1 sr
• Multiples and submultiples are expressed in • The SI system still permits the use
the decimal system of degrees (deg,°), where 1 circle = 360° 1 rad
• SI has only one unit for any physical quantity • The use of minutes and seconds is
and therefore no conversion factors or discouraged; decimal divisions of a degree
constants need to be remembered should be used THE STERADIAN (sr)
LENGTH (m)
• The SI unit of length is the meter (m) • The standard meter is currently defined as the length of 1,650,763.73 wavelengths (in a vacuum)
–7 of radiation corresponding to the unperturbed transition between the energy levels 2p and 5d
• Originally, it was 1 ¥ 10 of the 10 5
longitude passing through Paris from the of the Krypton-86 atom
equator to the North Pole • The wavelength of this orange-red line is 6.057 802 ¥ 10 –7 m
