Directions :
\nThe following eight (8) items consist of two statements, Statement I and Statement II. Examine these two statements carefully and select the correct answer using the code given below.
\nCode :
\nStatement I : Sound waves can travel through vacuum.
\nStatement II : Light is an electromagnetic wave and can travel through vacuum.<\/p>\n

[amp_mcq option1=”Both the statements are individually true and Statement II is the correct explanation of Statement I” option2=”Both the statements are individually true but Statement II is not the correct explanation of Statement I” option3=”Statement I is true but Statement II is false” option4=”Statement I is false but Statement II is true” correct=”option4″]<\/p>\n

\nThe correct answer is D) Statement I is false but Statement II is true.
\n<\/section>\n
\n– Statement I: Sound waves are mechanical waves. They require a medium (solid, liquid, or gas) for propagation because they travel through the vibration of particles in the medium. Vacuum is devoid of such particles, hence sound cannot travel through vacuum. This statement is false.
\n– Statement II: Light waves are electromagnetic waves. Electromagnetic waves do not require a material medium for propagation; they can travel through vacuum. This is why light from the Sun reaches the Earth through the vacuum of space. This statement is true.
\n<\/section>\n
\nElectromagnetic waves travel at the speed of light ($c$) in vacuum. Sound waves travel at much slower speeds, which depend on the properties of the medium.
