| Let there be Light! |
After a three entry that explain about science and technology. I think I should be writing about my main focus of doing this blog that is to explain what is light in the concept of science and technology. What is light? Except for knowing it's able to provide brightness. Do we actually knows what is the capabilities of "light"?
Light is just one portion of the various electromagnetic waves flying through space. The electromagnetic spectrum covers an extremely broad range, from radio waves with wavelengths of a meter or more, down to x-rays with wavelengths of less than a billionth of a meter. Optical radiation lies between radio waves and x-rays on the spectrum, exhibiting a unique mix of ray, wave, and quantum properties. (Source: What is light?)
Light is like other electromagnetic wave, light wave can interfere with each other. Meaning that even if light is travelling in straight line yet when they are directionally polarised the edge of the light will slightly bend in which that is practice in laser technology. Here is a video that will explain further regarding what light wave is.
