WILL GIVE BRAINLIEST IF CORRECT!!!
2 answers:
Answer:
wave A has a higher frequency than wave B
Explanation:
Frequency of a wave is number of waves that passes a fixed place in a given time
while wavelength is the distance between two successful crests of a wave as seen in the wave diagrams given
NOTE: The larger the wavelength the smaller the frequency

Explanation:
It is given that,
Wavelength of x-rays = 2 nm
Plane spacing, d = 0.281 nm
It is assumed to find the scattering angle for second order maxima.
For 2nd order, Bragg's law is given by :
For second order, n = 2
Here, θ is not defined. Also, the wavelength of x-rays is more than the plane spacing. It means that it cannot produce any diffraction maximum.
