Electromagnetic waves are generated through frequency oscillations which usually involve a coil of wire or in an extension such as a transmitting antenna. Lasers are light, formed in a coherent beam and generally don't exhibit electromagnetic waves.
Sound waves and electrmagnetic waves go through the atmosphere, to name two.
Electromagnetic spectrum is a diagram that show the range, or spectrum of electromagnetic waves, in order of wavelength, frequency and energy.
u figure it out dude
Surface waves travel slower than body waves.
sound are longitudinal waves while water waves are transverse waves
There is not any difference between tidal waves and tsunamis, except for that cyclones are high waves accompanied with heavy rain wheras tsunamis are only waves.
Sound waves are resulted due to vibrations.

Mechanical waves require a medium to travel, where electromagnetic waves do not.
Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit
False. The closer you are to the epicentre, the smaller the time difference between the arrival of P and S-waves.
