I. What is the difference between a standing wave in a string
and a wave that progresses within a string?
a) in a standing wave the location of maximums and minimums
along the string is constant in time.
b) in a wave that progresses the velocity of the wave changes
with time.
c) in a standing wave the wavelength is constant, whereas in a
progressing wave it is not
d) a standing wave is only created by having an external...
A wave in which the particles in the medium move perpendicularly to the direction that the wave travels along the medium is called a transverse wave. a longitudinal wave. a sound wave. a seismic wave a water wave.
What is the main difference between numeric variable and
categorical variable; the main difference between ordinal variable
and nominal variable; the main difference between ratio variable
and interval variable?
Both the light and radio wave are Electromagnetic Wave. Compare
the characteristics, applications and limitations of transmissions
systems based on light wave and radio wave.
A radio antenna broadcasts a 1.0 MHz radio wave with 29.0 kW of
power. Assume that the radiation is emitted uniformly in all
directions.
What is the wave's intensity 25.0 km from the antenna?
The answer is 3.69×10−6 W/m^2
What is the electric field amplitude at this distance?
