GENERAL KNOWLEDGE

Detailed explanation-1: -For visible light, the bluer part of the spectrum has shorter wavelengths, and the redder part of the spectrum has longer wavelengths. Thus, the Doppler effect for light is called a ‘blueshift’ if the light source is coming toward an observer, and a ‘redshift’ if it is moving away.

Detailed explanation-2: -A blueshift is any decrease in wavelength (increase in energy), with a corresponding increase in frequency, of an electromagnetic wave. In visible light, this shifts a color towards the blue end of the spectrum.

Detailed explanation-3: -This effect is called the doppler shift. If the object is coming toward you, the light is shifted toward shorter wavelengths, blue shifted . If the object is going away from you, the light is shifted toward longer wavelengths, red shifted . The amount of shift is bigger if the emitting object is moving faster.

Detailed explanation-4: -A hypsochromic shift is the shift of a peak or signal to shorter wavelength (higher energy). Also called a blue shift. For an absorption peak starting at max = 550 nm, a shift to higher wavelength such as 650 nm is bathochromic, whereas a shift to lower wavelength such as 450 nm is hypsochromic.
