3.3 Waves Flashcards
1
Q
What is the function of cladding?
A
to improve tensile strength of the fibre, prevent scratching, and prevent signal transfer between adjacent fibres
2
Q
What are diffraction gratings used for
A
calculating atomic spacing and analysing elements
3
Q
what is an example of a longitudinal wave
A
sound waves
4
Q
how do you prevent material dispersion
A
using monochromatic light
5
Q
what is an example of a transverse wave
A
electromagnetic wave
6
Q
What is Young’s Double-Slit Experiment
A
an experiment that demonstrates the diffraction of light by passing monochromatic light across two narrow slits and observing the resulting pattern of bright and dark fringes
