Introductory physics students like to call this ... the range will be the greatest at an angle of 45 degrees (since sin(90) = 1). Simple, right? Well, it’s not so simple to derive that ...

Everyone in freshman physics learns that the optimal launch angle for a projectile - the angle that makes a ball fly the farthest - is 45 degrees. But 45 degrees is the angle of a pitching ...

Plot a graph of sine of angle of incidence (y axis) against sine of angle of refraction. The gradient of this graph is the refractive index of the material of the semicircular block. So the ray ...

{sin\theta _{2}}\) When you use this relationship, angle \(\theta _{1}\) must always be the angle in a vacuum (or air). Refractive index depends on the frequency or colour of light. Light of ...

This is a cooler physics problem than I initially realized ... What if I take the same block and push up at an angle? Like this: Would I have to push harder or not as hard to keep the block ...
