Non-Lambertian sources are light-emitting surfaces that do not emit light uniformly in all directions, which is characteristic of Lambertian surfaces. Instead, they have directional emission patterns, meaning they may produce more light in specific angles or directions. Common examples include LEDs, lasers, and certain types of reflectors, where the intensity of emitted light varies with angle. This behavior is important in applications like lighting design and optical systems, where controlling light distribution is essential.

Which is a better source of energy conventional and non conventional sources of energy?

Non-conventional sources of energy are generally considered better because they are renewable and have lower environmental impacts compared to conventional sources such as fossil fuels. Non-conventional sources like solar, wind, and hydro power offer sustainable alternatives for the future.


How are renewable and nonrenewable energy alike?

Renewable energy sources use various non petroleum, non wood, non peat, non nuclear sources for fuel energy, typically to produce electricity. Petroleum, wood, peat, and nuclear energy are non renewable sources because they can be depleted faster than they can be replaced. The main way these energy sources are alike is they are all used to produce electricity.

Why is it necessary in todays world to use non conventional sources of energy?

we need these sources because these sources are recycle-able. This fact makes non conventional sources are most beneficial and useful. the conventional sources are very rare in this word and nearly will finished and these can't recycle.

Lambert's law for illumination?

This really belongs in "physics" or "optics", but there doesn't seem to be those categories. My best shot, given I'm not a physics professor: Lambert's Law says that the intensity of emmitted light from a surface is directly proportional to the cosine of the angle between the line of view and the normal to the surface. A Lambertian surface is a surface that follows this rule exactly. In practice, most surfaces are not perfectly Lambertian. This means that the light percieved from a Lambertian surface is constant, because while the radiant energy is smaller as the viewing point goes off 90° (straight-on; viewing angle = 0°; cosine = 1), the apparent area of the surface from that point of view is larger, so the same amount of light is percieved by the viewer.

Does Ontario rely mostly on non renewable or renewable sources of energy?

Most of Ontario's energy comes from non-renewable sources such as natural gas and nuclear power. While the province has been investing in renewable energy sources like hydroelectric and wind power, the majority of its energy still comes from non-renewable sources.
