AM Waves diffract more than FM waves.
Light waves do diffract, but the effect is very very small. In general diffraction effects are important when the object interacting with the wave has dimensions that are comparable to the wavelength of the wave. Light waves have much shorter wavelength compared to the radio waves. Hence the effect. (It should also be noted that radio waves penetrate buildings much better than light waves, but that leads to a more nuanced discussion of diffraction effects.)
remove the 2 plastic side panels. then you will see 4 small holes, insert a coathanger or other small object in to each hole and push away from the radio. then pull out the radio
RDS stands for Radio Data System. It is used to embed small amounts of digital information in FM radio broadcasts.
The small spark created by the contact of the switch created radio frequency waves that happen to included the frequency of your radio.
To find the serial number on an HD radio, look at the back or bottom of the radio. In most cases, the serial number is marked SN and is located on a small plate or tag at the bottom or back of the radio.
The light, passing though the lens of a projector is diffracted so that a small picture is projected as a large image.
Every city does not have to have tall buildings. Some small cities have small buildings. Besides, compared to NY and Chicago's skyscrapers nothing seems tall.
shed
I'm able to pull mine out by putting my fingers in the small compartment below the radio and my thumb on the top edge of the radio and pulling out from the dashboard. The radio is attached to the storage compartment with the antennae plugged into the back. Be carefull not to damage seal around radio when reinstalling.
The code is usually found on a small card and could be in or around the glove compartment. If it is not there you have to obtain the serial number of the radio and call the dealer for the code.

Many of the buildings in ghettos were multi-family apartments or small homes. These buildings were often made from poured concrete or concrete block.
buildings and small hut like homes
The best company that provides the best small buildings designs is Pine Harbor. You can purchase shed kits, small building designs and more from the Pine Harbor company.
The debris from the towers fell across large areas around the buildings' footprint. It was sufficient to trigger the collapse of other buildings and the adjoining streets were buried under the rubble that was once the two buildings. The dust, smoke and other small particles were spread across a far wider area.
House Sparrows tend to nest in and around buildings. They scavenge around domestic rubbish and also eat seeds. They are definitely attracted to bird feeders. They feed their young on small insects and inveterbrates.
The phone was kind of already a small radio its self, so it led to the invention of the radio, and on the radio you could hear weather reports and sometimes music.
