Molecules in many solids are arranged in a crystal lattice with distinct patterns and layers. These layers reflect and scatter light rays according to Bragg's law. The Bragg equation relates the distance, d, between layers of molecules to the angle, , of incoming light rays with wavelength Which of the following is the correct equation for the distance in terms of the angle and the wavelength?

Can (3,5 and square root 34) be sides on a right triangle?

Jonathan pays $1.90 per pound for potatoes. he buys 8.3 pounds of potatoes. he determines that he will pay $15.77, before tax, for the potatoes. which best describes the reasonableness of jonathan’s solution? jonathan’s answer is reasonable because there are two decimal places in the factors and two in the product. jonathan’s answer is unreasonable because there are three decimal places in the factors and two in the product. jonathan’s answer is reasonable because is 16, and 16 is close to 15.77. jonathan’s answer is unreasonable because is 8, and 8 is not very close to 15.77.
