... Put the Erlenmeyer flask into the warmer water (its temperature is measured by a thermometer) and wait some minutes so that the air inside has about the same temperature as the warmer water. Then – following the hints – put the drop of coloured water into the end of the pipe by use of the syringe. U ...

Unlike a wave on a string or a sound wave, electromagnetic waves do not require a medium in which to propagate. Electromagnetic waves can travel through a vacuum or through substances (depending on the absorptio ...

... Different cancer tumours are treated with different intensities of gamma radiation and so doctors place the source at different distances from the tumour. Intensity is also affected by the medium the radiation is travelling through. The denser the medium, the weaker the radiation gets. ...

... There are four basic lens shapes: double convex, double concave, plano convex and plano concave. In the 1830’s, the solution to chromatic aberrations was found by cementing two lenses made of different glasses (one double convex and one plano concave) together into an Achromatic Doublet to make a co ...

Light Rays
... The principal axis is the line passing through the optical centre and perpendicular to the lens. Rays parallel to the principal axis converge to or diverge from the focus or focal point of a lens. The principal focus is the point that rays parallel to the principal axis converge to (for convex l ...

With an atomic velocity of v ~- 1760 m/s, the interaction time between atoms and light is roughly 2wo/v = 44ns, significantly less than the 23p state natural lifetime of 100 ns.

F-number
In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography. The number is commonly notated using a hooked f, i.e. f/N, where N is the f-number.
