In the situations shown in Figure 25.3.3 25.3. 3, medium 2 has a greater index of refraction than medium 1. This means that the speed of light is less in medium 2 than in medium 1. Note that as shown in Figure 25.3.3a 25.3. 3 a, the direction of the ray moves closer to the perpendicular when it slows down.

Oct 19, 2023 · The index of refraction is a dimensionless quantity because, mathematically, it could be represented as a ratio between two different velocities – the velocity of light in a vacuum and the velocity of light in a given medium. It’s usually represented by ‘n’. The value of the index of refraction mostly comes out to be equal to or greater ...

As the ray travels through the glass and then crosses the boundary and encounters air it bends away from the normal (the dotted green line).; The incident ray of light is refracted away from the normal because the ray travels from glass, the slower, more optically dense medium with a higher refractive index into the air, a faster, less optically dense medium with a lower refractive index.
A simple example of (for practical purposes) unforced motion is provided by a symmetric, rigid object (such as a ball, or a wheel) rolling on a flat surface. The normal and gravity forces cancel each other, and since they lie along the same line their torques cancel too, so both \ (\vec v_ {cm}\) and \ (\vec L\) remain constant.

And \(e\) can be greater than 1 for so-called “explosive collisions,” where some amount of extra energy is released, and converted into kinetic energy, as the objects collide. (For instance, two hockey players colliding on the rink and pushing each other away.) In this case, the objects may well fly apart faster than they came together.
