Interference patterns do not have an infinite number of lines, since there is a limit to how big ‘m’ can be. what is the highest order constructive interference possible if the slit width is 0.01mm and wavelength 650nm?

tube or goog will be great resources to find the answer to the question that you're asking

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
