Using a difractometer and an x-ray source having a wavelength of 1.54 A degree one peak is observed for first order reflection from an FCC material when 2theta is 121 degree. What are the indices of this reflection? What is the interplanar distance?

What are the indices of this reflection? What is the interplanar distance?

What is the difference between reflection and refraction?

So i had to ask the same question with different account since i typo🤦‍♂️

Solve the following problems: i need complete solution please since i dont even understand how to do this and an explaination while youre at it.

1. Carl observed the continous flow of tide in the nearest beach at South Carolina 2 meters away from her distant area, every 3.7seconds and end at 18.5 seconds.
waves are forming twice as its flow from Carol's area. What is the frequency of the said numerous wave observed by Carl.

2. If the said period of wavelength is at 5m/s  and its time is at its peak of 15 seconds from its time. What is the velocity of its wave?

3. Give the following unit of its respective formula by changing the derived standard formula. Complete solution

a. # of Wavelength

b. time (frequency)

c. Lambda (h) of (Velocity)
