Answer:
The colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end. Visible light waves are the only electromagnetic waves we can
Explanation:
Answer:
585 nm
Explanation:
The formula that gives the position of the m-th maximum (bright fringe) relative to the central maximum in the interference pattern produced by diffraction from double slit is:
where
m is the order of the maximum
is the wavelength
D is the distance of the screen from the slits
d is the separation between the slits
The distance between two consecutive bright fringes therefore is given by:
In this problem we have:
(distance between two bright fringes)
D = 2.0 m (distance of the screen)
d = 3.0 x 10−3 m (separation between the slits)
Solving for , we find the wavelength:
When pushing a toy truck up an inclined plane, the force that makes the truck goes up is the force that the child uses to push the truck. (The force that pushes
Therefore the correct option is C.
Electromagnetic waves travel through a vacuum, Because it has an electric and a magnetic component in it.
<u>Explanation:</u>
The vibration that is created in an electric charge is the cause for the creation of an electromagnetic wave. The electromagnetic waves contains a magnetic and an electric component in it because of this vibration. The transportation of the energy at 3.00 x 108 m/s speed in an empty space.
The electric and magnetic components that are present in an electromagnetic wave is called fields. There is a vibration at an angle of 90 degree by these fields with respect to the wave motion. The light speed remains unchanged.
