Question

As compared to blue light what is the wavelength of red light

Answer 1

Answer:

Red light has a slightly longer wavelength than blue light. Red light (at one end of the visible spectrum) has a longer wavelength than blue light. However, another way of distinguishing between the different colors of light is by their frequency, that is, the number of waves that pass by a point every second.

Answer 2

As compared to blue light , the wavelength of red light is more.

Explanation:

Visible spectra has colours violet, indigo, blue, green , yellow, orange and red arranged in order of decreasing energy.

As we know energy and wavelength are related as:

$E=\frac{hc}{\lambda}$

where,

E= energy

c = speed of light  

$\lambda$  = wavelength of the wave

Thus the light having higher energy will have low wavelength and vice versa.

Thus wavelength of red light will be more as compared to wavelength of blue light.
