Mechanical And Electromagnetic Waves:
Mechanical and electromagnetic waves can be
distinguished depending on the medium. Electromagnetic waves travel
without the use of a medium, whereas mechanical waves require the use of one.
Mechanical waves do not travel in a vacuum, whereas electromagnetic waves do.
Waves can be
categories into…….types on the basis of medium?
a) two
b) three
c)
four
d) six
Explanation: 1. Mechanical waves and
2. Electromagnetic waves
Which of the
following waves only travel through a medium?
a) electromagnetic
b) mechanical
c) both of them
d) none of them
Explanation:Waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium.
Which of the
following waves can travel through a vacuum (without medium)?
a) electromagnetic
b) mechanical
c) both of them
d) none of them
Explanation:Electromagnetic radiation consists of waves of the electromagnetic field, which propagate through space and carry electromagnetic radiant energy. It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays.
Which of the
following waves travel with speed of light?
a) electromagnetic
b) mechanical
c) both of them
d) none of them
What is the speed of electromagnetic waves in vacuum in km per second?
a) 300
b) 3000
c) 30000
d) 300000
