Light is an electromagnetic wave whose frequency is approximately from 4 × 10
14 〖 〗 〖 〗 × 10
8 to.14 Hz, or a wavelength in the range 400 to 700 nm. The human retina sensitive electromagnetic this range. Very high temperature objects such as stuffed lamp with a maximum temperature of roughly 300 Kelvin.

Light is electromagnetic radiation with frequencies ranging from approximately 4 × 〖10〗 〖10〗 ^ ^ 14 to 8 × 14 Hz or a wavelength in the range 400 to 700 nm, the human eye is more sensitive to radiation. Subject to high temperatures, such as incandescent light bulb with a maximum temperature of about 300 Kelvin.

The light is electromagnetic waves whose estimated frequencies since 4 × 〖 10 〗
