This occurs when the hole diameter is equal to the square root of twice the wavelength (λ) times the distance (f) between the pinhole and film—i.e., Square root of√2λ f. For f = 100 millimetres and λ = 0.0005 millimetre, the optimum hole size becomes 0.32 millimetre. This is ...

Pythagorean Theorem: The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. Mathematically, it can be represented as: a² + b² = c² where...
To calculate it, one can subtract the mean from each data point, square the result, sum all the squared values, and divide by the total number of observations in the population. Population variance is a statistical measure that describes the spread or dispersion of data points in a specific ...
Math has a separate place among all subjects. A student must have some basic knowledge about math whether he or she belongs to the arts, science or commerce stream. Having some basic ideas about math will not only help to secure good marks in the academic exam but will also help you in...

Phylogenetic generalized least square regressions83support a strong, negative and highly significant correlation between T:L ratios and each of the TL evenness and Brillouin indices (Supplementary Figs.6and7and Supplementary Table3). The seemingly linear decrease in TL Brillouin and evenness values with...
