Suppose a sound wave and a light wave have the same frequency.
2 answers:
Answer:
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.

Answer:
6 m/s
Explanation:
Given that :
mass of the block m = 200.0 g = 200 × 10⁻³ kg
the horizontal spring constant k = 4500.0 N/m
position of the block (distance x) = 4.00 cm = 0.04 m
To determine the speed the block will be traveling when it leaves the spring; we applying the work done on the spring as it is stretched (or compressed) with the kinetic energy.
i.e
v = 6 m/s
Hence,the speed the block will be traveling when it leaves the spring is 6 m/s
