Answer:
Explanation:
wavelength, λ = 0.86 nm = 0.86 x 106-9 m
velocity of electromagnetic radiation is same as the speed of light
v = 3 x 10^8 m/s
Let the frequency is f.
The relation between the wave velocity, wavelength and frequency.
v = f x λ
[tex]3 \times 10^{8}= f \times 0.86 \times 10^{-9}[/tex]
[tex]f=3.488 \times 10^{14}Hz[/tex]
The another radiation has frequency, f = 6.4 x 10^11 hz
Let the wavelength is λ.
The relation between frequency, wavelength and the velocity is given by
v = f x λ
[tex]3\times 10^{8}=6.4 \times 10^{11}\times \lambda[/tex]
λ = 4.6875 x 10^-4 m = 0.46875 mm
The range of frequency for the X rays lies between 10^16 Hz to 10^19 Hz.
The above radiations do not lie between this range so they are not detected by the X ray detector.
The distance traveled by the radiation in the time is d .
distance = speed x time
d = 3 x 10^8 x 0.38 x 10^-12 = 1.14 x 10^-4 m
