wavelength of the EM wave produced by your iclicker is 0.33 m.
<h3>What makes an EM wave?</h3>
- When an electric field (illustrated in red arrows) combines with a magnetic field, electromagnetic waves are generated (which is shown in blue arrows). An electromagnetic wave's magnetic and electric fields are perpendicular to each other and to the wave's direction.
- A changing magnetic field causes a changing electric field, and vice versa—the two are inextricably related. Electromagnetic waves are created by changing fields. Electromagnetic waves, unlike mechanical waves, do not require a medium to propagate.
The clicker emits EM (electromagnetic) wave which travels at the speed of light, that is
v = 3 x 10⁸ m/s
The frequency is
f = 900mHz = 9 x 10⁸ Hz
velocity = frequency * wavelength, the wavelength, λ, is given by
fλ = v
λ = v/f
= (3 x 10⁸ m/s) / (9 x 10⁸ 1/s)
= 1/3 m = 0.333 m

Answer:
Insight
Explanation:
In psychology insight has been described as a sudden knowledge or solution that just came up especially after several attempts to solve the problem.Like Amira after spending two hours to solution and she has given up before the solution finally came up. Answers or solutions from insights are more reliable that non-insightful answers.
Gestalt Psychology, a 20th century psychologist was the first to carry out as study on insight where he saw it as a sudden seeing the problem in a new way or linking the problem to other problem or solution pair or release certain blockages prevent one from seeing the solution etc.

Answer:
c. The group speed is less than the phase speed.
Explanation:
For an individual the speed is given by v phase = w/k
w is angular frequency and k is wave number.
This is called phase speed. Group speed is the speed of wave packet.The rate of advance of a crest on a single wave point which is fixed phase.
