refractive index is determined by the formula – R = Sin i Sin r Where i = angle of incidence of the ray of light r = angle of refraction of the ray of light The refractive index of a medium gives the light bending ability of the material. When light passes from one medium to another it is bent‚ the extent to which it is bent depends on the value of the refractive index of the material. When light passes from one material into a material with greater refractive index (optically

Keith Joung‚2‚3‚4 and Toni Cathomen1 Abstract Zinc-finger nucleases (ZFNs) are a powerful tool that can be used to edit the human genome ad libitum. The technology has experienced remarkable development in the last few years with regard to both the target site specificity and the engineering platforms used to generate zinc-finger proteins. As a result‚ two phase

------------------------------------------------- Refractive index From Wikipedia‚ the free encyclopedia In optics the refractive index (or index of refraction) n of a substance (optical medium) is a dimensionless number that describes how light‚ or any other radiation‚ propagates through that medium. Its most elementary occurrence (and historically the first one) is in Snell’s law of refraction‚ n1sinθ1= n2sinθ2‚ where θ1 and θ2 are the angles of incidence of a ray crossing the interface between

The Pros and Cons of Passive Management Ever since the introduction of passive index funds in the mid-1970s‚ there has been an ongoing debate over the merits of active versus passive management of pension fund assets. Each year articles chronicle the relative rise and fall in popularity of each approach to portfolio management. The advantages and disadvantages of each approach vary with the size of the portfolio as well as with the characteristics of the asset classes. In fact‚ there may be a place

explained to me and did this project with me in group. INTRODUCTION TO INDEX NUMBERS An index number is an economic data figure reflecting price or quantity compared with a standard or base value. The base usually equals 100 and the index number is usually expressed as 100 times the ratio to the base value. For example‚ if a commodity costs twice as much in 1970 as it did in 1960‚ its index number would be 200 relative to 1960. Index numbers are used especially to compare business activity‚ the cost

ratio. The Herfindahl index‚ another indicator of firm size‚ has a fair amount of correlation to the concentration ratio. The four-firm concentration ratio is an indicator of the size (as measured by output or sales) of the four largest firms within an industry‚ compared to the output of the entire industry. It is determined as follows: CR4=(X1+X2+X3+X4)/T where Xn is the output of the nth largest firm and T is the total output of the industry.

To answer this question we need to find out how to turn dollar into consumer price index (a relevant unit which measures the overall cost of goods and services purchased by a customer) to be able to compare cost of living over the time.

In Form 4‚ we have learnt about Index Number from Chapter 11 in Additional Mathematics. Do you know what exactly Index Number is? Well‚ an index number is an economic data figure reflecting price or quantity compared with a standard or base value. The base usually equals to 100 and the index number is usually expressed as 100 times the ratio to the base value. For example
