The wavelength, which represents the size of the smallest detectable detail that uses ultraviolet light , is calculated as follows: 3× / 1.72×
or approximately 1.74×
m.
The distance between the two positive, two negative, or two minimal points on the waveform is known as the wavelength of the wave. The following formula expresses the relationship between the frequency and wavelength of light:
f = c / λ
where, f = frequency of light
c = speed of light
λ = wavelength of light
Given data = f = 1.72×Hz
Therefore, λ = 3× / 1.72×
λ = 1.74×m

Answer:
a) frequency is 2.381 Hz
b) the angular frequency/speed is 14.96 rad/s
c) the magnitude of the magnetic field is 0.5199 T
Explanation:
Given that;
cross sectional Area A = 0.018 m²
Number of turns N = 200
from the diagram. maximum time T = 0.42 sec
a) the frequency f of the generator in hertz
frequency = 1 / T
we substitute
frequency = 1 / 0.42 = 2.381 Hz
Therefore, frequency is 2.381 Hz
b) the angular frequency in rad/s
angular speed ω = 2πf
we substitute
ω = 2π × 2.381
ω = 14.96 rad/s
Therefore, the angular frequency/speed is 14.96 rad/s
c) the magnitude of the magnetic field.
to determine the magnitude of the magnetic field, we use the following expression;
e = NBAω
from the diagram, e = 28.0 V
so we substitute
28.0 V = 200 × B × 0.018 × 14.96
28 = 53.856B
B = 28 / 53.856
B = 0.5199 T
Therefore, the magnitude of the magnetic field is 0.5199 T
