Consider the following about electromagnetic and mechanical waves. Justify your answer

Which of the following types of wave can be transmitted through space, where there is no air? Choose all that apply. Justify your answer briefly. Visible light Radio Waves Gamma Rays Sound waves A tuning fork vibrating in air produces sound waves. These waves are best classified as: Transverse, because the air molecules are vibrating parallel to the direction of wave motion Transverse, because the air molecules are vibrating perpendicular to the direction of wave motion Longitudinal, because the air molecules are vibrating parallel to the direction of wave motion Longitudinal, because the air molecules are vibrating perpendicular to the direction of wave motion Radio waves and gamma rays traveling in space have the same: Frequency. Wavelength. Period Speed Which type of wave exhibits the Doppler effect? Choose all that apply. Justify answer briefly, Visible light Radio Waves Gamma Rays Sound waves

Explanation / Answer

a) visible light, radio waves, gamma waves are electromagnetic waves. so they transmit with out require a medium. but sound waves requires a medium . sound waves are not transmit in the vaccum

b) longitudinal , becauses the air molecules vibrate parallel to the wave motion

c) same speed. electro magnetic waves are moving with eaual to speed of light

d) sound waves exhibit doppler effet .
