Light is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light has wavelength in a range from about 380 nanometres to about 740 nm, with a frequency range of about 405 THz to 790 THz. The speed of light in a vacuum, 299,792,458 meters per second (about 300,000 kilometers per second), is one of the fundamental constants of nature. Light, which is emitted and absorbed in tiny "packets" called photons, exhibits properties of both waves and particles. This property is referred to as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics.
Miniature lighbulbs on rosy copper headpins. Gilded with golden foil. 2.5" including wires. Convo me if you'd like ear wires changed to hypoallergenic material or other style such as leverback or clip-on.
I ship Priority, which is safe and fast. However, recently International Priority has become extremely expensive. If you convo me letting me know you will accept any losses or damages, I can ship domestic for $2, Canada for $3.50, Mexico for $5.20 and everywhere else for $6.
