Yes it is it is btw there is no picture if you were meaning to put one
Answer:
462 nm
Explanation:
Given: width of the slit, d = 5.6 × 10⁻⁴ m
Distance of the screen, D = 4.0 m
Fringe width, β = 3.3 mm = 3.3 × 10⁻³ m
First dark fringe means n =1
Wavelength of the light, λ = ?
An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionized gas (plasma).
Answer:
Energy of ultra violet photons < Energy of radio waves
Wavelength of ultra violet photons > Wavelength of radio waves
Explanation:
The increasing order of the wavelength is given by
Gamma rays
x rays
Ultra violet rays
Visible radiations
Infrared rays
micro waves
Radio waves
So, ultra violet rays has larger wavelength than radio waves.
As we know that the energy is inversely proportional to the wavelength.
So, the energy of radio waves is more than the energy of ultra violet waves.
Energy of ultra violet photons < Energy of radio waves
Wavelength of ultra violet photons > Wavelength of radio waves
Answer:
Explanation:
Let the separation required be d .
Force between rod = 10⁻⁷ x 2 I₁ I₂ L / d
where I₁ and I₂ are current in them , d is distance of separation and L is length of wire .
Force between rod = 10⁻⁷ x 2 x 1200 x 1200 x .69 / d
= .1987 /d
Restoring Force by spring = k x where k is force constant and x is compression .
= 130 x .03
= 3.9 N
For balancing
Restoring Force by spring = Force between rod
.1987 /d = 3.9
d = .1987 /3.9
= .0509 m
= 5.09 cm .
