Answer 1

Answer:

radio waves, microwaves, infrared, visible light, ultraviolet light, X-rays, gamma rays

Explanation:

Electromagnetic waves are oscillations of electric and magnetic fields in a direction perpendicular to the direction of motion of the wave (transverse waves). They are classified into 7 different types, according to their frequencies.

From lowest to highest frequency, we have:

Radio waves $<10^9 Hz$

Microwaves $10^9 Hz - 4\cdot 10^{13}Hz$

Infrared $4\cdot 10^{13} - 4\cdot 10^{14} Hz$

Visible light $4\cdot 10^{14} - 8\cdot 10^{14}Hz$

Ultraviolet $8\cdot 10^{14} - 2.4\cdot 10^{16} Hz$

X-rays $2.4\cdot 10^{16} -5 \cdot 10^{19}Hz$

Gamma rays $>5\cdot 10^{19} Hz$
