Question

The subjective property of light related to wavelength is _________ (colour, refractive index).

Answer 1

To answer the given question of the subjective property of light related to wavelength; we should go through the concept of the properties of light that are related to the wavelength. Subjective properties will be discussed more in the solution.

Complete step by step solution:
The form of electromagnetic radiation that emits a bright source is known as Light. Light is a kind of kinetic energy that makes us see the object that is present in front of our eyes. Light obeys the laws of reflection that state the angle of incidence is equal to the angle of reflection. When a light ray travels from one medium through other, the velocity of the light changes, and hence refraction of light takes place. To measure the refraction of the light refractive index is used.
The process in which the white light disperses into several different colors when passed through the prism-based on their wavelengths is known as Dispersion. The light bends around the corner of the small obstacles and it encroaches into a smaller geometric process called Diffraction.
When the normal light travels in all possible directions. If the light's vibrating direction is perpendicular to the direction of propagation and when it vibrates on one particular plane then the light is said to be a polarized light. Interference of the light takes place when one or two light waves impose on each other.
These are the subjective properties of the light. From the given information the subjective property of the light that is related to the wavelength is Colour.
Hence color is the correct answer.

Note: Every color that is dispersed from the light has different wavelengths. Different wavelengths are perceived as different colors to the human eye. According to this, visible light is divided into seven different colors. The seven bands are called VIBGYOR and it is the acronym of seven different colors with different wavelengths.
