White light is passed through a diffraction grating that has the spacing between the slits of 4x10^6m. on each side of the white central maximum, a spectrum of colors is observed. what is the wavelength of the light observed at an angle of 7.00° in the first-order bright fringes?

The wavelength of the light is 487477.37 m.

Explanation:

Given that,

Spacing between the slits

Angle = 7.00°

We need to calculate the wavelength

Using formula of wavelength

Where, d = distance between the slits

n = order bright fringes

Put the value into the formula

Hence, The wavelength of the light is 487477.37 m.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
