Answer:
equal to 1
Explanation:
When any ray of light falls or strikes on a surface, the ray is reflected back and the angle of reflection is equal to angle of the incidence, where both the angles are always measured from the path of light that is normal to surface of the point at which the ray of light strikes the surface. This is called as the laws of reflection of light.
And therefore, the ratio of the angle of incidence to the angle of reflection is always equal to 1.
The sequence of types of electromagnetic radiation is arranged from that with the least to the most energetic photons will be visible light , ultraviolet, x-rays, gamma rays.
<h3>What is electromagnetic radiation?</h3>
Electromagnetic radiation is a type of energy that is transmitted in incident photons as both magnetic and electric waves.
Electromagnetic radiation has a spectrum with varying wavelengths and frequencies, which gives it different properties.
Electromagnetic radiation is a type of energy that travels in packets of energy called photons as both electrical and magnetic waves.
Wave-particle duality is the name given to this phenomenon. This is a notion that defines how a wave behaves whether it behaves like particles, waves, or both particles and waves.
Hence the sequence of types of electromagnetic radiation is arranged from that with the least to the most energetic photons will be visible light , ultraviolet, x-rays, gamma rays.
