Question #5fa05

Answer 1

Light has properties of both waves and particles; it can be described as both an electromagnetic wave and as a photon, the carrier particle of the electromagnetic force.

---

Light is electromagnetic so it consists of oscillating electric and magnetic fields.

The visible part of the spectrum has a wavelength range of `3.7 × 10^-7 — 7.4 × 10^-7 m`.

All electromagnetic waves have a speed of `3.0 × 10^8 \ m\ s^-1` in a vacuum.

Light can be reflected, refracted, diffracted, polarised ( polarized in US English), and superposed.
