The colour are characterized by which of the following:- 1. Frequency. 2. Amplitude. 3. Wavelength. 4. Velocity?

Question

Answer

Frequency

Answer

Characteristics of Colors

1. Frequency

Frequency is the number of times a wave oscillates per unit of time. In color, frequency determines the perceived hue. Colors with higher frequencies appear bluer, while those with lower frequencies appear redder.

2. Wavelength

Wavelength is the distance between two successive crests or troughs of a wave. In color, wavelength determines the perceived shade or tint. Colors with longer wavelengths, such as red, appear warmer, while those with shorter wavelengths, such as blue, appear cooler.

3. Amplitude

Amplitude is the height of a wave's crest or depth of its trough. In color, amplitude determines the perceived brightness or intensity. Colors with higher amplitudes appear brighter or more intense, while those with lower amplitudes appear duller or less intense.

4. Velocity

Velocity is the speed at which a wave travels through a medium. In color, velocity determines the perceived saturation or purity. Colors with higher velocities appear more saturated or pure, while those with lower velocities appear less saturated or mixed with other hues.

Therefore, the characteristics of colors are determined by their frequency, wavelength, amplitude, and velocity, which collectively determine their perceived hue, shade, tint, brightness, intensity, and saturation.

Answer

Wavelength

Answer

Colour is a function of human visual system and is not an intrinsic property. object's don't have colour, they give up light that appears to be a colour. these are characterized by wavelength (or frequency) and intensity.

Answer

Light is a electromagnetic wave .According to ncert the classification of electromagnetic waves according to frequency is electromagnetic spectrum .And for a particular E.M wave the wave varies according to medium.
