A cold wave typically starts when a high-pressure system traps cold air near the Earth's surface, causing temperatures to drop significantly. This cold air mass then moves into a region, displacing warmer air and causing temperatures to remain below average for an extended period of time.

What is difference between loo and cold wave?

A heatwave, often referred to as a "loo," is an extended period of excessively hot weather. A cold wave, on the other hand, is a prolonged period of significantly cold weather compared to the seasonal average. Both can have adverse effects on human health and the environment.


How high must a wave be to break in water that is 7.8 meters deep?

Generally, a wave will start breaking when the water depth is about 1.3 times the wave height. So, in water that is 7.8 meters deep, a wave would likely start breaking around 6 meters in height.


You are creating a wave on a spring if you start shaking more slowly the wavelength of the resulting wave will?

Increase


What indicates that a water wave transfers energy to a floating object?

When a water wave approaches a floating object, the object will start to oscillate or bob up and down due to the transfer of energy from the wave to the object. This transfer of energy causes the object to move in response to the passing wave.


As a wave nears the shore its characteristics begin to change when the water depth is half of its?

When the water depth is half its wavelength, waves start to interact with the seabed, causing them to slow down and increase in height. This transformation is due to the decrease in water depth, which causes the bottom of the wave to start feeling the seabed's resistance. This interaction can also lead to the wave's crest bending forward, creating a breaking wave as it approaches the shore.
