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.

the device is called “ rocket engine”

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
