What are at least two differences between ultraviolet rays and microwaves?

Microwaves are electromagnetic radiation with frequencies in the range from 300 MHz (0.3 GHz) to 300 GHz although some sources restrict their definition to the 3 GHz to 300 GHz range.
Ultraviolet rays are electromagnetic radiation with wavelengths in the range from 10 nm to 400 nm (frequencies from 2.99x107 to 7.5x105 GHz)
Clearly the frequencies are quite different.
Also - since the frequencies are so different, UV filters may not filter microwaves and vice-versa. Sunblock may protect you from getting a sunburn from UV rays but it won't block microwaves at all. Similarly, absorption of the two forms of radiation is quite different. Microwaves can heat a cup of soup up very nicely while you could die of starvation waiting for UV rays to heat it up.

How is the electromagnetic spectrum divided?
The Electromagnetic Spectrum consists of: (From least intense to most)Radio WavesMicrowavesInfraredVisible LightUltraviolet LightX-RaysGamma Rays
Do you measure photons energy with wavelengths?
you see how close the wavelengths are-- the closer, the more powerful it is. Here are the wavelengths- from least powerful to most powerful: Radiowaves, Microwaves, Infared Waves, Visable Light, Ultraviolet, X-rays, and Gamma rays.
What is the wave length of an ultraviolet wave?
From the related links: between about 10 nanometers (most energetic Extreme Ultraviolet) to about 300 nanometers (least energetic Near Ultraviolet). Visible violet light is about 400 nanometers.
What are the physical differences between polar and nonpolar molecules?
polarity... polar is the mid- range; nonpolar is the least polar.
How do you Least to greats blue light X-rays microwaves orange light infrared radiation?
If we list the electromagnetic energy from lowest energy (lowest frequency) to highest, we list them microwaves, infrared radiation, orange light, blue light and X-rays.
Types of electromagnetic energy from least energetic to most energetic?
microwaves < infrared < visible < ultraviolet < x-rays < gamma rays .
The radio waves with the shortest wavelengths and highest frequencies are called what?
From longest wave length to shortest (least energy to most, lowest frequency to highest) the spectrum is: Radio & TV - Microwaves - Infrared - Visible Light - Ultraviolet - X-Rays - Gamma Rays

What moves faster an x ray or a microwave?
All electromagnetic waves move at the same speed, at least in vacuum. X-rays and microwaves ... as well as radio, infrared, ultraviolet, heat, and visible light ... are all electromagnetic waves, and travel at the same speed.
