INTRODUCTION

Do different wave lengths of light affect the growth rate of mung beans

(Vigna Radiata)? So what are wave lengths? A wave length is the distance of which a wave of light travels from one point to another. The wavelength is measured by nanometers for example in this experiment blue light has a wavelength of 475nm and red light with a wavelength of 650nm. Plant growth requires water and light for it to be able to grow, The research aims to discover which light is more efficient for plant growth. The ERD can help farmers in the future to grow plants faster and more effectively.

Hypotheses

If the plant is exposed to light with shorter wavelengths (covered in blue cellophane) then it will grow faster

If a plant is exposed to longer wavelngths (covered with red cellophane) then it will grow slower than the plant exposed to shorter wavelengths.

METHODOLOGY

Materials

-3 recycled cups

- mongo seeds (10 per cup)

- Red cellophane

-Blue cellophane

-Soil

Procedure

Name the cups A,B and C

Plant ten seeds into each cup

On the 8th day cover cup a with blue cellophane Cup b with red and Cup c no cover

Measure and observe the plants from the 10th to 20th day

III Data and analysis

The height of the plants measured in Centimeters

IV Conclusion

The researchers have concluded that exposing the mung beans to blue light resulted to better growth rates. The best light for better growth rates are lights with shorter wavelengths. The plant exposed to the longer wavelengths yielded better growth rates than the control plant (no cover).

V. Recommendation

The researchers recommend that for more comprehensive testing to use different species of plants and observing them longer so that the results will be more accurate and precise. Try using more colors to test light with different wavelengths. One researcher Daniel recommends that further research on the type of soil and proper planting of the seeds his seeds we're planted but did not germinate at all so the researcher recommends planting the seeds not that deep so that the seeds can germinate and not die. These are the recommendations and suggestions of the researchers to further improve the ERD in the future.
