Suppose a sound wave and a light wave have the same frequency.
which of the following is true?

the light wave has a shorter wavelength and has the slower speed.
the light wave has a longer wavelength and has the slower speed.
the sound wave has a shorter wavelength and has the greater speed.
the light wave has a shorter wavelength and has the greater speed.
the sound wave has a longer wavelength and has the slower speed.
the light wave has a longer wavelength and has the greater speed.
the sound wave has a longer wavelength and has the greater speed.

The light wave has a longer wavelength and has the greater speed.

Explanation:

light has a far more greater speed than sound. The speed of sound in air is about 343m/s while that of light is around  

wavelength (λ) =

since the frequencies of sound and light are same from the question, the wavelength would depend on the magnitude of their velocities. Light with a higher speed would have a longer wavelength.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
