Question

What do radio waves and gamma rays have in common?

A - They are both electromagnetic waves.

B - They are both low frequency waves.

C - They can only travel in a vacuum.

D - They both are part of the visible light spectrum

Answer 1

A- They are both electromagnetic waves

I took the test and this was the answer

Step-by-step explanation:

Answer 2

A - They are both electromagnetic waves.

Step-by-step explanation:

Electromagnetic waves are waves consisting of periodic oscillations of electric and magnetic fields, that vibrate in a plane perpendicular to the direction of propagation of the wave (for this reason, they are said to be "transverse waves").

Electromagnetic waves, unlike mechanical waves, can travel through a vacuum, and do not need a medium to propagate. Their speed in a vacuum is a constant and it is called speed of light (
`c=3.0\cdot 10^8 m/s`).

Electromagnetic waves are classified, depending on their wavelength and frequency, into 7 different types - together they form the electromagnetic spectrum. The 7 types, listed from shortest to longest wavelength, are:

gamma rays

X-rays

ultraviolet radiation

visible light

infrared radiation

microwaves

radio waves

All these waves, despite having different properties, are all electromagnetic waves -so we see that both radio waves and gamma rays belong to this type of waves.
