Ared laser pointer shines on a diffraction grating, producing a diffraction pattern on a screen behind the grating. if the red laser pointer is replaced with a green laser pointer, will the green bright spots on the screen be closer together or farther apart than the red bright spots were?

Closer together

Explanation:

A red laser pointer shines on a diffraction grating, producing a diffraction pattern on the screen behind the grating. In diffraction grating the width of the the diffraction pattern is proportional to the wavelength of light used. Since the wavelength of green light is smaller than red therefore, the width of the pattern is smaller. Hence the green light spots will appear closer.

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;
