Answer #1

1) Wavelength of electromagnetic energy sensitive to human eye is 0.4 to 0.8 m.

2) Blue colour is produced due to wavelentghs ranging from 0.4 to 0.5 m.

3)Green colour is produced by wavelengths ranging from 0.5 to 0.6 m.

4) Red colour is produced by wavelengths ranging from 0.6 to 0.7 m.

Note-I have produced the values in m and may vary slight due to significant figures.These wavelengths are mostly measured in nm .If you have any doubt regarfding this,please ask before rating.Thanks
