6.1(i) The glass core is surrounded by a plastic cladding.State and explain which material has a higher refractive index and explain your answer..[2](ii)The light ray enters the air-glass interface at 45°.Calculate the angle of refraction in the glass core.angle of refraction =...[2]...
The critical angle for an air-glass interface is 29.6^o. When a light ray in air is incident on the interface, the reflected ray is 100% polarized. What is the angle of refraction of that ray? A light ray is reflected from a mirror with an angle 25.0 to the normal. What was ...
What is Bernoulli's equation? What is a conserved quantity in an explosion? What is damping and what factors does it depend on? What is len's maker equation? What is displacement? What do you understand by displacement equation? What is the equation: x = x_0+v_{0t}+\frac{1}{2}at...
aDeclare what? 宣称什么?[translate] aExplain why diamond are so bright.Be sure to explain what a critical angle is,and the use of total internal reflection. 解释为什么金刚石是很明亮的。请务必解释什么一个临界角是和对总内部反射的用途。[translate]...
Equation solvers:Advanced scientific calculators may include equation solvers for finding roots of linear, quadratic, or even polynomial equations. Unit conversions:Easily convert between different units of measurement, such as length, mass, and temperature. ...
As it is shown in the first part of this short essay, duality plus conservation laws allow the violation of Bell’s inequalities for any spatio-temporal separation. To dig deeper into particle dualism, in the second part, a class of models is proposed as a working framework. It encompasses...
Therefore the matrix in (1) has rank at most , and hence has determinant zero as claimed. For instance, if we know that and , then in order for to be coplanar, the remaining distance has to obey the equation After some calculation the left-hand side simplifies to , so the non-...
where is the unknown field. In analogy to pseudoconformal symmetry, we have conformal symmetry: if solves (3), then the function , defined in the interior of the light cone by the formula also solves (3). There are also some direct links between the Schrödinger equation in dimensions...
When it comes to the global trend nowadays - artificial intelligence and machine learning, the first thing we care about is data. A machine learning model's life starts with data and ends with the deployed model, and turns out that high-quality training data is the backbone of a well-perfo...
In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics. Trigonometry The use of sine, cosine, and tangent ratios to solve geometric problems. Finding the angle of elevation to ...
