FE1002 PHYSIC 2 Tutorial 1– [optic] 2007/2008 Semester 2 FE1002 Physic 2 Tutorial 1 – Optic QUESTION 1: light with a wavelength of 700nm is incident on the face of a fused quartz prism (n = 1.46 at 700nm)at an angle of 75˚ (with respect to the normal to the surface). The apex angle of the prism is 60.0˚. Calculate the a) b) c) d) angle of refraction at this first interface angle of incident at this second interface angle of refraction at the second interface and angle between the incident and

than the tropical grassland. The Simpson Indices‚ as defined in Cuevas et. al (2012)‚ is based on dominance and as the number of dominant species in a community are few‚ the species has low diversity. The tropical rainforest ecosystem showed a higher index of dominance than the tropical rainforest resulting to the higher values it obtained in the Simpson Indices of Similarity and Evenness. This means that most of the dominant organisms present in the grassland are quite similar and the same due to the

Snel’s Law is used to calculate the path of waves to compute the angles of incidence and refraction. • The law is also used in metamaterials‚ which allows light to be bent ’’backwards’’ at a negative angle of refraction with a negative refraction index. What is refraction? • Deflection from a straight path undergone by a light ray or energy wave in passing obliquely from one medium into another‚ in which the velocity is different. • Refraction occurs when a beam of light is bent and is caused

Introduction The term "teenager" started being used in the 1940s. After the depression‚ young men and women were able to stay in school longer than previous generations. For the first time there were large groups of kids aged 15 to 18 that found themselves in the same place. This created the social class of the teenager. (http://www.123helpme.com/view.asp?id=54045).

ECONOMIC GOALS INTRODUCTION What are economic goals? How do economic goals affect our lives and what are its implications to sustain stability? These questions will be answered based on the materials gathered‚ learned insights from Miss Nur Shalihah Muhdi‚ my lecturer for this subject‚ and using some issues particularly in the country Malaysia. It is a common knowledge that each country is centered by its government who paved way the economic system. Economy as to be the basis of the topic is

Why has DFA’S small stock fund performed so well? 3. Why has DFA’s small stock fund performed so well? We conclude 6 reasons for the stellar performance of DFA’s small stock funds: 1) Distinct Investment Strategies. Dimensional founders believed passionately in principle of "passive" stock market investing. As passive investors believe in the so-called efficient market theory‚ which maintains that almost no one can be smarter than the market as a whole in the long run. Hence DFA buy and hold

This case looked at the operations of the Vanguard Group‚ the mutual fund industries growth leader. Unlike some of its competitors‚ Vanguard has been able to attract and retain clients without an extensive marketing campaign. Recently there has been discussion about implementing a more direct sales marketing campaign. However‚ given their extremely low expense ratios and their ability to consistently outperform the industry‚ there are some concerns over the financial issues that would accompany
