The correct answer to the question is- Sound waves i.e the sound waves can not move through vacuum.

EXPLANATION:

Sound wave is a mechanical longitudinal wave which requires a medium for its propagation. The medium may be solid,liquid or gas. It can not travel in space or vacuum.

As per Clark Maxwell's electromagnetic theory, the electromagnetic radiations are the waves which contain time varying electric and magnetic fields which are perpendicular to each other as well as perpendicular to the direction of propagation. Any electromagnetic wave can travel in space with the velocity of light i.e $3\times 10^8\ m/s$ .

As per the question, we have X-ray, gamma ray,visible light and sound wave.

Except sound, all the waves i.e visible light, gamma ray and X-ray are electromagnetic in nature. So, these waves can travel in space.

Hence, the correct answer of this question is sound wave which can not travel in space or vacuum.

Sound waves cannot travel through a vacuum. sound waves are mechanical. because the are mechanical they can not move through a vacuum due to their propagation they require oscillation of matter.

Suppose an oven's radiation wavelength is 0.125 m. a container with 350.00 g of water was placed in the oven, and the temperatur

ivann1987 [24]

The heat (energy) needed to raise the temperature of the water is given by
$Q=m C_S (T_f - T_i)=(350.0 g)(4.18 J/gC)(80C-20C)=87780 J$

The wavelength of the radiation of the oven is $\lambda=0.125 m$ , so the energy of a single photon of this radiation is
$E=h \frac{c}{\lambda}=(6.6 \cdot 10^{-34}J) \frac{3\cdot 10^8 m/s}{0.125 m}=1.6 \cdot 10^{-24} J$

So, the number of photons required to heat the water is the total energy absorbed by the water divided by the energy of a single photon:
$N= \frac{Q}{E}= \frac{87780 J}{1.6\cdot 10^{-24}J}= 5.5 \cdot 10^{28}$ photons
