when the two waves interfere with eachother to make a dark spot the periodic difference of the two waves is π . the wave length for 2π is 600nm
. ie. for π difference it is 300nm
No, they actually travel through the vacuum of outer space, but it also requires the absence of a material sedium.
The magnetic field on the sun is created by <u>flowing charged plasma</u> a liquid iron core flowing charged plasma friction iron in the solar wind.
Plasma, a gas-like state of matter in which electrons and ions have separated to produce a very hot mixture of charged particles, makes up the sun. Magnetic fields are naturally produced as charged particles move, and these fields have an additional impact on the motion of the particles.
Because the magnetic fields above the surface of the sun direct the travel of that plasma and cause the loops and towers of material in the corona to shine brilliantly in EUV photos, we can see the shape of the magnetic fields there.

Answer:
10
Explanation:
Given that :
Initial Velocity (u) = 25 m/s
Range can be obtained using the relation :
Range = (u² * sin2θ) / g
g = 10m/s ; θ = 45
Range = [10² * sin2(45)] / 10
Range = [100 * 1] ÷ 10
Range = 10
Answer:
Explanation:
We shall apply length contraction einstein's relativistic formula to calculate the length observed by observer on the earth . For the observer , increased length will be observed for an observer on the earth
L= 2.05
The length will appear to be 2.05 m . and width will appear to be .5 m to the observer on the spaceship. . It is so because it is length which is moving parallel to the direction of travel. Width will remain unchanged.
