ultrasonic sound waves
Bats produce ultrasonic sound waves to sense obstacles in their environment. These waves bounce back, allowing bats to navigate and locate objects in the dark.
Ultrasonic sound waves
Bats use high-frequency sound waves, called echolocation, to sense obstacles in their environment. They emit these sound waves which bounce off objects, allowing the bat to receive and interpret the echoes to navigate and locate prey.
Sound waves do not produce sharp shadows due to their ability to diffract around obstacles, resulting in a gradual decrease in intensity rather than a distinct shadow. Water waves can produce sharp shadows in certain conditions, such as when the obstacle is large relative to the wavelength of the waves, leading to a clear blockage of the wave energy.
Radio waves hit all obstacles the same, but the waves will differ in the distance of the wave and/or the object from the transmitter.
They produce ultrasonic waves.
AM radio waves have longer wavelengths compared to FM radio waves, allowing them to diffract or bend around obstacles such as buildings and hills. This enables AM radio waves to travel greater distances and provide better coverage in areas with obstructions. FM radio waves, on the other hand, travel in straight lines and are more affected by obstacles.
no but the reason they can be heard so far away is because the sound waves travel much farther than higher pitch sound waves. google image sound waves. since lower ones are flatter they can do this and they can penetrate through physical obstacles. for example whales communicate with low frequency sounds and thus they can talk to a fellow whale miles and miles away
Diffraction is the bending of waves around obstacles and the spreading of waves as they pass through apertures. The amount of diffraction depends on the wavelength of the wave: shorter wavelengths produce less diffraction, while longer wavelengths produce more pronounced diffraction effects.
sound waves dont produce vibrations, vibrations are sound waves.
Diffraction of sound waves is more easily observed because sound waves have longer wavelengths compared to light waves. This allows sound waves to diffract around obstacles more effectively, producing noticeable effects like the bending of sound around corners or obstacles. Light waves, with their shorter wavelengths, tend to diffract less noticeably and require specific conditions to observe diffraction effects.
