Homework Answers
All of the listed options are valid... As frequency is inversely proportional to wavelength hence sound waves have lower frequencies and higher wavelengths ... Sound waves needs medium to travel while light can propagate in vacuum and sound waves are longitudinal and light waves are transverse ..
So all the options given are valid...

The photoreceptors in the human eye, called rods and cones, have different sensitivities to different wavelengths of electromagnetic waves. (Figure 1) (Notice that the y axis in the figure is a logarithmic scale.) The rods, which number over 100 million, can only be activated by a certain range of wavelengths, but they do not pass any color information to the brain. In other words, they note differences in shades of grey (from black to white) and are responsible for a...
