The material property that determines a material's spring effect is the elastic modulus. The flexural modulus is based on both the elastic modulus and the geometry of the part. The elastic modulus of steel is 200 GPa, for polymers it is much much less than that. So without either reinforcing the...

Should work, waves travel through all solids. It is an interesting experiment though. You may get a different response based on the material used due to the difference in in the speed of sound in the material. Try both!

The simplest model would be to talk about crystalline metals. Two of the most common crystal structures (FCC and BCC) have 74% and 68% of the space filled with atoms and the rest is free space (the space between the atoms). This model assumes that all atoms are spheres of equal size. Actually...

For Bragg's Law you have nλ = 2dsinθ. This corresponds to when constructive interference of the diffracted x-rays occurs. You can also see from this equation that constructive interference depends on both the x-ray wavelength (λ) and the atomic spacing (d). It's the same for light diffraction or...
