about light on plant growth (1 Viewer)

[HSC_vege-Bird]

i am currently doing an assessment in regard to that topic.
Light quality refers to the wavelength of the light, it's like blue, red and green. e.t.c

how do i set the experiment up?

like, do i purchase coloured light bulb. but i am not sure whether the color at the surface of the light ball will alter the light quality. Or do i jus purchase Fluorescent light bulb which is rich in blue and incandescent which is rich at red colour?

bio is somewhat remembering than common sense xP
just use one light and put a transparent, but coloured sheet over the light
(the ones you use in primary)

Cellophane

use no cellophane and green cellophane as it absorbs green light

There is a bit like this in the biochemistry option.
They used a glass prism to split white light into the different colours. This gives the different wavelengths of the visible spectrum.

This is true, its easy to crack high 90s in bio with an hour to spare if you just memorise everything.
