Question

Describe the difference between red light and blue light. Describe the difference between red light and blue light. 700 nm corresponded to light in the red range and 450 nm corresponded to light in the blue range. 450 nm corresponded to light in the red range and 700 nm corresponded to light in the blue range. Red light can be produced by only neon and blue light can be produced by various elements. 700 nm corresponded to light in both red and blue ranges but different light speed. 450 nm corresponded to light in both red and blue ranges but different light speed.

Answer 1

Answer:700 nm corresponded to light in the red range and 450 nm corresponded to light in the blue range.

Explanation:The wavelengths of the visible spectrum are usually between 400 nm and 700 nmn with the the rays of red light having a longer wavelength, and blue light rays having shorter wavelengths. The red light has a low frequency of about 405–480 THz and , blue light has a higher frequency in the range of 620–680 THz.  This is due to the inverse relationship between wavelength and frequency which also occurs betwwn  wavelength and energy of light rays with the  red light having less photon energy of about  1.65–2.00 eV and the  blue light with high energy photons of about 2.64–2.75 eV.

Red light can be employed in the photosynthesis in plants as it helps in formation of flowers and the production of fruits. Blue light also is important in the production of chlorophyll and can cause a healthy and strong stem and leaves in excess exposure.
