Of the waves listed, the one
with the longest wavelength is the radio wave. The answer is letter B. They are
the longest wave in the electromagnetic spectrum. It can either be a long wave
or a short wave.
The y-component of the initial velocity vector is zero only in scenarios A and C. The weight/package on either plane inherits a non-zero x-component that matches the plane's horizontal velocity, but with respect to the vertical direction the objects are at rest, and dropping them from a given height doesn't confer them an initial vertical velocity. On the other hand, if the object was thrown upward and allowed to fall, or shot downward by a cannon, then the initial vertical velocity would be non-zero.
In scenario B, the dolphin must have some non-zero y-component of velocity in order to launch itself out of the water, because otherwise it would stay at a fixed depth.
A common application of the wave/particle duality of ligt is in the technology of the solar panel.
<h3>Photoelectric effect</h3>
One of the greatest breakthroughs of mordern physics is the establishment of the fact that light could both behave as a light and a particle. The ressearch into the particle nature of light gave rise to the phenomenon of the photoelectric effect.
Now, a very popular application of this is in the solar panel where light impinges on a metal panel which is connected to a battery that can be used to store charges.

A booklet is a small book—with fewer pages and smaller dimensions than a “real” book, and usually a paper cover.
