Document Summary

Regional geography: an interactive approach to compare regional geographic variation. A region: an area of the earth"s surface defined by distinctive physical and/or human characteristics. Physical characteristics: location, landform, climate, soil, natural vegetation. Human characteristics: cultural, socio-economic, political, demographic, urban and rural: regions are dynamic due to continual changes. Population and economic power are shifting west (moving from quebec and ontario towards bc and western canada) Power of aboriginal population increasing (use of media to convey their problems/concerns) How and why does regionalism exist? size and natural division: north/south orientation (bc trades with west coast states maritimes trade with east coast states, distinct cultures (french quebec, aboriginal groups) Political dimension (bna act, provinces work independently from federal government on certain issues: uneven population distribution. Environmental determinism: the assumption that the physical environment determines human behaviour. Power of place: emphasizes a region"s natural wealth, geographic situation and access to global markets.

Prob. 2. Two converging lenses, A witha focallength of +2.0cm and B

with a focal length of +5.0cm, areplaced 14cmapart. An object is

place 3.0cm to the left of lensA.

A) Use graphical methods, to scale, toconstruct theray diagram

with a measurement of the final imageposition andheight; and

B) Use the lens equation determinethecharacteristics of the

image.

Prob. 3. A prism with angles 45Â°,45Â°, and 90Â° is tobe used to turn a

beam of light through a 90Â° angle.What is theminimum index of

refraction for the material of theprism that willgive the total

internal reflectionneeded?

Prob. 4. A tarantula is sitting 4.5min front of aconcave spherical mirror

with radius of R =1.4m.

A) Construct a ray diagram to scaleshowing theobject, image and

the mirror. Determine graphicallythecharacteristics of the image.

B) If the image is 5.0cm tall, howhigh is thetarantula?

Prob. 5. A Youngâs double slitapparatus has theslit separation of

0.12mm and the distance between theslits and theviewing

screen is 55 cm.

A) If monochromatic light ofwavelength Î» = 550x10-9mpasses

through the slits, calculate thedistance betweenthe central

(bright) fringe and the adjacentbright fringe.

B) Now imagine that you are usingX-rays, Î»=1x10â9minstead of

visible light in this experiment. Whatwould theslit separation

need to be in order to have thedistance betweenthese first two

bright fringes be1cm?

Prob. 6. Acombination of blue light (n=1.60) andred light (n=1.50)is

incident on the surface of a flatglass plate.Because of dispersion

there are two refracted rays. Draw adiagram showingthe incident

and both refracted rays, indicatingthe red and theblue rays.

Calculate the angle between therefracted blue andred rays.
