IGCSE Grade 10 Science Infrared radiation and electromagnetic spectrum
|
These surfaces absorbs all wavelengths of light that falls on it.
These radiations raise the temperature of the object wherever they fall.
Speed = wavelength \\(\\times\\)frequency
Speed = wavelength \\(\\times\\)frequency
This also helps in measuring the heat released by infrared radiation.
Exhibiting these properties they are called as transverse waves
The frequency of these radiations lies between 300GHz - 3KHz
Hotter objects absorb more infrared radiation.
Infrared waves are also referred as heat waves, Sun is the main source of UV rays
The elctromagnetic spectrum provides all types of electromagnetic radiations with respect to wavelengtth and frequency
