How does sonar detect underwater objects?
Sonar works by sending out sound waves that travel through the water and bounce off objects. The sonar system then detects the echoes of these sound waves as they bounce back and calculates the distance, size, and shape of underwater objects based on the time it takes for the echo to return.
What allows us to hear sounds underwater?
The soundwaves caused by sounds made underwater, disrupts the water molecules causing them to vibrate. These vibrations hit our ear drum and is processed into our brain as sounds, but since the vibrations in water are slower then vibrations in air the sounds sound more obsure then if it were not in water.
How does penguins hearing compare to humans?
Penguins have better underwater hearing than humans, as they rely on sound to communicate and find prey in the ocean. They are able to hear a wider range of frequencies and are more sensitive to sound vibrations underwater. However, on land, penguins' hearing abilities are similar to those of humans.
How do marine animals navigate?
Cetaceans depend on sound to some degree to sense the ocean environment, and some are known to use echolocation. Echolocation allows these animals to determine the distance of objects (food, predators) and features of the underwater environment (seafloor depth, topography) for navigation purposes. They accomplish this by projecting sounds, called sonar clicks, that are reflected back when the sounds strike an object. The farther away an object is, the longer it takes for the echo to return, allowing the echlocating animal to tell the distance. Echolocation makes it possible to navigate and feed at night and in deep or murky water, or at great distances where visual sensing would be ineffective. For example, a dolphin can detect a target the size of a golf ball almost a football field away, much farther than the dolphin can see underwater. Marine mammals also use underwater vocalizations to communicate with each other. Because sound waves travel efficiently in water, some ocean-dwelling animals are able to communicate over great distances through sound. Based on the few marine mammal species for which hearing has been tested to date, it appears that a given species' hearing is tuned to a broad range of frequencies with the greatest sensitivity typically encompassing the range of vocalizations and echolocation (for echolocating species).

What can frogs hear underwater?
They will simply hear what is around them. Sound, which is vibrations, can travel in water, air and through anything apart from a vacuum.Whilst underwater, frogs hear sound waves that have been emitted by other frogs and ambient noises also. Frogs use internal ears to process sound signals as well as their lungs, although the sensitivity of the lungs is not as high as that of the ear structure.They can hear fish, insects, animals and other frogs that are in the water. They hear using their big round ears called tympanum. Frogs can hear under water through the vibration that travels through the water, but they cannot hear sounds that are short and of high frequency.
Can Echoes occur underwater If so how?
Yes, echoes can occur underwater. When a sound wave hits an object, such as the seabed or a submerged object, the sound wave bounces off and returns to the source, creating an echo. The depth and composition of the water, as well as the frequency of the sound wave, can affect the strength and clarity of the echo.
How does density affect the transmission of sound?
The higher the density of an object, the harder it will be for the sound to be transmitted through the object.
Is there sound underwater?
Yes, sound can travel underwater, but it travels differently compared to in air. Sound waves travel faster and farther in water due to its higher density, allowing marine animals to communicate and navigate using sound.
What is the sound affect that the Beatles use in their songs yellow submarine and octopus garden?
It was the sound of the movement of a chain underwater.
Why can't you hear underwater?
Sound waves accessible by humans are attenuated in water.
How does sonar affect divers underwater?
Sonar can disrupt the navigation and communication of divers underwater, potentially causing disorientation and confusion. The sound waves from sonar can also disturb marine life and affect their behavior.
How does the density of the material in the beaker affect how long the sound continued to be heard after the beaker was tapped?
IF the density is low, then there will be an echo
Why does the sound of a person's voice sound different underwater than when they speaking through air?
Sound travels faster in water than in air, which changes the way the sound waves travel through the medium. This difference in speed and density causes the pitch and tone of the sound to be altered, making a person's voice sound different underwater compared to in the air.
What factors affect the speed of sound in a medium?
The speed of sound in a medium is affected by several factors, including the density and elasticity of the medium. Generally, sound travels faster in materials with higher elasticity and lower density. Temperature and pressure also play a role in influencing the speed of sound.
What three properties of a medium affect the speed of a sound?
The three properties of a medium that affect the speed of sound are elasticity, density, and temperature. Answered by: Nur _ _ _ _ _ _ Izyani
What is the significance of Julia's underwater sound in the film?
Julia's underwater sound in the film serves as a metaphor for her inner turmoil and emotional depth. The sound represents her struggle to navigate her feelings and experiences, as well as her desire to break free from the constraints of her environment. It adds a layer of complexity to her character and highlights the complexity of human emotions.
How does water affect waves?
Water makes sound slower and if it goes through matter it goes faster
