A wave could be transverse or longitudinal. We like to think in terms of whole waves. This is when a particle comes back to it's original position and direction of movement. For transverse waves, we can s...

To answer this question we need to know what makes glass different to air. The main difference is their refractive index. For air it's 1 and for glass it's anywhere between 1.52 - 1.54 depending on the t...

f(x) = 7xe^xUsing the product rule: [f'(x)=u*(dv/dx)+ v*(du/dx)]Let u=7x and v=e^xTherefore, du/dx=7 and dv/dx=e^xHence, f'(x) = 7xe^x + 7e^x
