What will waves look like for a quiet sound?
Sound waves that are very tall and deep will be very loud, and sound waves that are short and shallow will be very quiet (Figure 1). The distance between the crests and valleys will determine the frequency, or what is commonly known as the pitch of the sound. …
What makes a sound quiet?
Sounds can be loud or quiet. Bigger vibrations make louder sounds, and smaller vibrations make quieter sounds.
How loud or quiet sound is?
Loudness refers to how loud or soft a sound seems to a listener. The loudness of sound is determined, in turn, by the intensity of the sound waves. Intensity is a measure of the amount of energy in sound waves. The unit of intensity is the decibel (dB).
What does a soundwave look like?
The Details: For a pure sound of only one frequency, like a tuning fork or whistling, the wave looks smooth and regular (as in the picture below). These are called sine waves. High notes have a high frequency and the waves are very close together. Low notes have a low frequency and the waves are spread out.
What if we could see sound?
The result is an image of the sound’s movement, depicted as a shifting mist –what they call a “sound-form”. Jenelle says the technique is particularly suited to memorialising special moments: her first sound-form was of her baby’s foetal heartbeat.
Can we see with sound?
Sound is a vibration, or wave, that travels through the air. Sound waves are invisible to our eyes; unless we find a way to make the sound waves move something that we can see.
Can humans see sound?
The vibrating motion of most sound waves is far faster than your waving hand, and is therefore just a blur to human eyes. The sound waves traveling down a plucked guitar string are not invisible. They are just moving so fast that the plucked guitar string looks like a blur to our human eyes.
Can humans and animals see the sound?
Turning conventional neuroscience on its head, new research suggests the human visual system processes sound and helps us see. Human laughter may trace its evolutionary beginnings to vocalizations made during play. This type of “laughing” is found in many mammals and even in some birds.
Can animals see things we cant?
So far we have looked at how to study animal senses that we humans also possess. But some animals can detect things that we cannot sense at all. In fact, some creatures can see forms of light that we cannot. There are plenty that can see ultraviolet, which is light with a wavelength of between 100 and 400 nanometres.
What animals communicate with sound?
Animals like bats, dolphins, shrews, some whales and some birds all use sound—echolocation—to see in the dark. Bats and bugs game (could also substitute dolphin and fish for bats and bugs). This is similar to the game Marco Polo. Have youth form a circle and choose one or more youth to be the bats and blindfold them.
Which animal can survive for more than two years without food?
Tardigrades, which are also known as space bears or moss piglets, are able to survive for up to 30 years without food or water and endure temperature extremes of up to 150 degrees celsius, the deep sea and the frozen vacuum of space.
What animal has 32 brains?

The tiny kangaroo rat found in the south western deserts of the united states does not drink water in its entire life. Kangaroo rats are an important part of desert life.
What animal has no blood?
Flatworms, nematodes, and cnidarians (jellyfish, sea anemones, and corals) do not have a circulatory system and thus do not have blood. Their body cavity has no lining or fluid within it. They obtain nutrients and oxygen directly from the water that they live in.

Is human blood really blue?
Maybe you’ve heard that blood is blue in our veins because when headed back to the lungs, it lacks oxygen. But this is wrong; human blood is never blue. The bluish color of veins is only an optical illusion. Blue light does not penetrate as far into tissue as red light.
Do snails have blood?
Snails consist of blood to 20 to 50 %, the sea hare’s (Aplysia) body weight is about 75 % blood. Most snails’ blood pigment is haemocyanin. Contrary to haemoglobin, used by vertebrates, haemocyanin works on a complex with copper as oxygen binding atom.
Do snails have 2 Hearts?
Circulation and Excretion A snail’s heart has two chambers, one ventricle and one atrium. It is located in the heart bag, the so-called pericardium. The heart bag is also important to the snail’s excretion, meaning the disposal of indigestible material usually rich in nitrogen.
