What is the wave length of amber & yellow colour
~600 nm
650nm
orange
Sound waves are much longer then light waves.
The colour of visible light with the longest wavelength is red (approximately 700 nanometres).
Low amplitude
650nm
orange
The color red has the longest wavelength of any color.
Compared to yellow light, orange light has: A LONGER WAVELENGTH!
Compared to yellow light orange light has a longer wavelength.
It can be any hue of orange to yellow depending on the wavelength of the light.
There are seven colors in a rainbow. Listed from top to bottom, these are: red, orange, yellow, green, blue, indigo, and violet. The color with the longest wavelength is red. After this, the color with the next longest wavelength is orange, then yellow, green, blue, indigo, and violet.
Bright Orange-RedA normal commercial aircraft's "black box" is orange. It was likely chosen because orange has the longest wavelength after red. As the wavelength increases, the wave travels a longer distance. Seeing that red is already reserved for Danger signs, what follows after red is... orange.
Towers are painted in orange and white rather than red and white..... as the red colour has the highest wavelength but it's specified for the DANGER sign...hence the next longest wavelength colour 'orange' has been chosen....therefore, to increase the visibility of the tower.

red
When the electrons that are excited by the energy of burning drop back into lower energy levels they emit light at that orange wavelength.
