Electrons carry a negative charge.
Answer:
214.3 x 10⁻⁹ m or 214.3 nm
Explanation:
= slit separation in the experiment = 3.00 x 10⁻⁵ m
= screen distance from the slits = 2.00 m
= Order of the bright fringe = 7
λ = Wavelength of the light
= distance of the bright fringe from the central bright fringe = 10 cm = 0.10 m
Position of the bright fringe is given as
λ = 214.3 x 10⁻⁹ m
λ = 214.3 nm
Answer:
Horizontal distance moved by the person is 3.2 m
And it is independent of the mas of the person
Explanation:
As we know that the speed of the people when it is sliding downwards is given as
Now the time taken by the person to hit the water surface is given as
horizontal distance moved by the person is given as
Answer:
Microwaves are a type of wave that are sandwiched between radio waves and infrared radiation on the electromagnetic spectrum. In the case of microwave ovens, the commonly used wave frequency is roughly 2,450 megahertz.
