How does a fisherman use sonar?
To find shoals of fish by bouncing sound waves off them. And;To check the state of the bottom if trawling, and also to avoid going aground- by bouncing sound waves off the sea bottom.
How would you use refraction in a sentence?
The location of the fish in the water is not where it seems to be, due to the refraction of light in the water.
Why do you have waves?
Tsunami's occur because of under water earthquakes,landslides and rockfalls. Some can also occur because of under-water eruptions of volcanoes. <><><><> However, most ordinary waves are caused by wind blowing over the water.
Water in a wave moves what and what?
Well . . . boats, shallow swimmers and fish, and energy can all do that.
What are some common examples of refraction?
Refraction is the bending (changing direction) of light (or other wave) as it passes from one medium to another. Waves also change speed when refraction occurs. Most of the examples of refraction that people encounter in daily life involve light and either glass or water, but all waves exhibit refraction, including sound and water. 1. A relatively pure example of refraction can be observed if one places a straight object like a pencil partly in a glass of water and then observes the apparent change in the direction of the image of the straight object when it crosses the surface of the water. 2. A prism is an example of refraction. It also illustrates that the extent of refraction of light depends on the color. In a prism, light is refracted as it enters and as it leaves the prism and the light waves of different colors change directions by different amounts so that when they exit the colors are seen at different angles. 3. Rainbows have color because of refraction in a manner similar to a prism. The rainbow results when light waves encounter drops of water. There is also reflection involved and a full explanation is more complicated than the case of a prism. 4. All lenses (including the lenses in eye glasses) function because of refraction. Light enters the lens on one side and because the surface of the lens is curved, the angle of light inside is different depending on the place on the lens surface where it entered. That is called focusing light. It happens again as the light exist the lens. The eye itself has a lens that operates because of refraction and creates the image on the retina of the eye. 5. When you look into water, the objects that you see are not in the location where the image appears. Native peoples who hunted fish with a spear learned that you do not through the spear at the image of the fish because the angle of the light changes coming out of the surface of the water and makes it appear as though the fish is slightly displaced. 6. Sound refracts as does any other wave. One can not easily notice this, but if you are under water and sound enters from the air, the apparent direction will shift by some angle. 7. Water waves refract and it is easily demonstrated with a co-called ripple tank. When the depth of water changes, so does the speed of a wave. In a ripple tank one can place a flat surface on the flat bottom of a tank so there are two different water depths separated by a straight edge. Waves creates in one depth that encounter the edge at an angle will be seen to change direction. This is most obvious for very shallow depths around a centimeter. 8. Ocean waves change speed and so also demonstrate refraction but it is not clearly seen unless there is an edge such as described for the ripple tank. Ocean waves are a different sort of wave than a ripple but still can show diffraction. One can obviously see the change in speed and wavelength of waves as they come to a shore and that is related to the refraction process. 9. In old glass windows the glass is sometimes not very flat and ripples in the glass are evident. (Ripples in water give the same effect.) When you view an image through rippled glass the image is distorted because that light that entered was bent when it came in at an angle different than it was bent on the way out. The bending is refraction and the same kind of refraction as with a lens, but the ripples are irregular where as a lens is carefully smoothed.
when the angler fish waves its light?
my sis made this
What is the phenomena of ocean waves lighting up at night called?
The phenomenon of ocean waves lighting up at night is called bioluminescence. It is caused by the emission of light by some organisms, such as deep sea fish and fireflies.
Do fish have brain waves?
yes
What are the names of fishes that produce light?
john( the fish produces light ), Mary ( the fish produces light ), ,Toby ( the fish produces light ), may ( the fish produces light ),
Whats the effect that waves do to fish?
scarellet
One thing that fish do not share?
one thing that fish don't share is behavior. every fishes behavior is different from other. i have a fish tank full of fish they all act different to me.
What is the basic principle of a fish finder?
Fish finders are great tools for fishers. With the help of sound waves the fish finder emits sounds waves that when they hit something go back to the receiver. Based on the time taken by the sound wave the fish finder understands whether there is a fish.
Where do light fish live?
light fish live in the artic ocean
Are glow fish fresh water fish?
Yes a glow fish is a freshwater fish. They are a relatively small (between 1 and 2 inches) schooling fish which means that they need to be in groups of 5 - 6 or more. You can buy them at your local pet store but they are more expensive than other schooling fish. they are about 4-5 dollars each (prices vary) because of their glowing properties. These fish do not glow in regular light, but are still pretty because of their neon yellow green or pink/red colors. They only really glow under a black light. You can buy a tank specifically for glow fish with a built in black light at your local fish store as well.
Does water cast a shadow?
It depends on how you define shadow. If you define shadow as an area of lessened light caused by objects in the light path, then yes water can and does cast shadows, esp. waves, ripples, etc.
What happens if you get the mystery chemical in fish tycoon?
If you use it, your fish will change or develop certain properties.
Why do fish go crazy when you tap the tank?
When u tap into the fish tank, you cause tiny waves to form that scare the fish.
