Now it may also be related that light bends in a denser media compared to a rarer media because an additional rotational force is working. In other words, the definition of straight line has to change in the medium, that is of different density, because path of light is changing. Light is the guy who suffers the least when something tries to buzz it, because its inertial property of mass is zero. The curvature of light or the bending or deflection known as Refraction is thus a measure of the sideways force or energy.
Thus speed of light in different media is a measure of this bending or curvature and is known as Snail’s law ( — Pun intended, its actually; Snell’s Law — ) . Automatically when distance and time have to readjust, to produce an angle or bending, known as refraction ( — possible because distance and time can produce an angle if they are equivalents — ) the speed must also change.
All these are inter related. Light refracts and its speed changes, in relative change in density of media because there are rotational or non-inertial effects.
( — or additional energy is available, or a force is acting to bring a curvature in light’s path, perhaps the electromagnetic effects of the molecules? Its not only distance or time that are equivalents, read one article of mine “All You Need To Know About Relativity” to understand; how energy and time and distance and in short all Physical Variables are equivalents of each other — ) More…
Teaching is therefore while creative, satisfying and attractive in many respects and suitably rewarding one must be devoted in as many angles as it requires to be successful and responsible keeping the motto of teaching in glaring memory: teaching produces tomorrow’s citizens, the spearheads and pioneers of tomorrow’s world is the just product of today’s education and a teacher is the most relevant architect for that purpose.
I also look at teaching and learning process from another angle of paramount importance. Research. Teaching devoid of the latest knowledge of a body of epistemology, a creative dint of heuristics never discovered before or a suave deviation from a canonical pedagogy cannot be effective or attractive. One therefore in almost all academic branches be inclined to persevere to invent or share such gained insights by others towards the student-body. An ideally inspired student with an appetite to grow and cultivate the action of learning is not only the need of academia but also a cornerstone of a progressive society. More…
Liliana has a bag of marbles. The bag contains 18 black,
15 red, 11 blue, and 8 white marbles. Liliana randomly takes
a red marble from the bag and leaves the marble on a table.
What is the probability that she will next take a red or a white
marble from the bag? More…
The equation v = a*del_t is sometimes used
to find velocity when acceleration and
time are known. Another form of this
equation is v = v_0 + a*del_t. In this second
form of the equation, the function of the
term v_0 is to:
A. indicate that the equation is valid
only for an object that starts at rest.
B. determine the time at which
velocity is equal to zero.
1. A ball is thrown with an initial velocity of 20 m/s at an angle of 30°
above the horizontal. What is the instantaneous vertical velocity of
the ball when it is 5.1 m above the release point? (g = 9.8 m/s^2)
A. 0.2 m/s
B. 6.6 m/s
C. 10 m/s
D. 17 m/s More…
1. Which of the following best describes the
most widely accepted theory of the solar
A. A small star grew as it consumed
comets, eventually becoming large
enough to ignite fusion reactions
and attract planetary bodies.
