Answer:
The answer is
The wavelength of the light is 557.2 x 10⁻⁻⁹nm
Explanation:
The wavelength of a wave is the distance between adjacent troughs and crests while the frequency of a wave is the number of completed cycles that pass a given per unit time
Electromagnetic radiation, such as light is usually described n terms of its frequency and wavelength
The equation relating the three quantities of speed of light, frequency and wavelength is as follows
Speed of light, c = Frequency of the light wave, ν × Wavelength of the light, λ
That is c = ν × λ
Where c = 299792458 m/s, v = 5.38 x 10¹⁴ Hz
Therefore the wavelength = = 5.572 x 10⁻⁷ m 557.2 x 10⁻⁻⁹nm
Answer:The answer is because of the gravity and the mass formed in the sun, the magnetic field reacts to it and leaves a fault on earth. wind goes by the earth and procides to be ok
Explanation:that is it
Explanation:
Given that,
Induced emf
Rate of current = 0.250 A/s
Number of turns =30
(a). We need to calculate the mutual inductance of the pair of coils
Using formula of the mutual inductance
The mutual inductance of the pair of coils is 6.6 mHz.
(b). We need to calculate the flux through each turn
Using formula of flux
Put the value into the formula
The flux through each turn is
(c). We need to calculate the magnitude of the induced emf in the first coil
Using formula of induced emf
The magnitude of the induced emf in the first coil is
Hence, This is the required solution.
