Answers

Answer 1

Answer:

1. Rainbow (white light is split into its subsequent wavelengths)
2. Light enters through the cornea, is adjusted by the lens, the cones and rods of the retina are responsible for the perception of color and shadows, which are sent through the optic nerve to the occipital lobe of the brain.

3. Sound waves are intercepted by the pinna, travels through the auditory canal, reverberates on the eardrum, the vibrations travel through the ossicles of ear (hammer, anvil and stirrup), continuing to the cochlea and are sent through the auditory nerve to the brain.

4. A medium

5. Vibrations

6. All

7. Faster

8.Their kinetic energy increases

9. Conduction, convection and radiation

10. The heating of metals in the mantle, creates a current which slowly moves the plates above it.

Two or more waves combining to produce a wave with a smaller displacement is called _____. A. constructive diffraction

B. constructive interference

C. destructive interference

D. destructive diffraction

Answers

Two or more waves combining to produce a wave with a smaller displacement is called destructive interference .

What is the definition of destructive interference?

Destructive interference happens when the maxima of two waves are 180° out of phase a positive displacement of one wave is canceled exactly by a negative displacement of the other wave.

The formula for brighter patches resulting from constructive interference and darker patches resulting from destructive interference in a diffraction grating is:

$\rm d sin \theta = n \lambda$
