3. A diffraction grating G has 800 lines mm-¹ and is illuminated normally by parallel monochromatic light of wavelengths 560 nm and 590 nm. G Calculate the angle 8 between the first order maxima of each wavelength on one side of the normal.

Describe at least one other factor that affects the transparency of materials except for transmission, absorption, scattering, reflection, refraction, and diffraction.

the normal human eye can detect colors whose wavelengths range from 380 nm to about NOTE: 1 n m = 10 − 9 m ( o r 1 m = 10 9 n m ) Group of answer choices 600 nm. 750 nm. 550 nm. 650 nm.

X-rays of wavelength equal to 0.134 nm give a first order diffraction from the surface of a crystal when the value of 0(theta) is 10.5°. Calculate the distance between the planes in the crystal parallel to the surface examined. Solve correctly please full explanation needed
