When a wave transfers from one medium to another with different properties, the speed of the wave can change. In this case, we know that the wavelength changes when the wave transfers from the first type of rope to the second type of rope. If the wavelength becomes one-fourth of what it was before the transfer, this means that the second type of rope has a higher wave speed than the first type of rope.
The wave speed is defined as the product of the wavelength and the frequency of the wave. Since the frequency of the wave remains constant as it transfers from one medium to another, a decrease in wavelength means an increase in wave speed. This can be seen from the wave equation, c = λf, where c is the wave speed, λ is the wavelength, and f is the frequency.
Therefore, if the wavelength becomes one-fourth of what it was before the transfer, this means that the wave speed in the second type of rope is four times the wave speed in the first type of rope. In other words, the speed of the wave becomes quadruple its original speed after the transfer.

When you're playing Angry Birds on your smart phone, you likely don't realize how important science is to what you're doing. As the birds catapult through the air, science is probably the last thing on your mind. Aside from the physics involved in sending feathered projectiles flying through the air, there's a far deeper connection between science and playing your favorite games. That's because all technology, from smart phones to medical scanners to cars, are intimately connected with science. Without science, they wouldn't exist.
Science is the study of the natural world by collecting data through a systematic process called the scientific method. And technology is where we apply science to create devices that can solve problems and do tasks. Technology is literally the application of science. So it really is impossible to separate the two. In this lesson, we're going to go into a little bit more detail about how science and technology are related, including some examples.
Answer:( Related to the weather)
dressing for the forecast. seeing a flag blow. preparing for a hurricane. (Related to Technology) turning on the lights. riding in a car or bus. downloading a song.
Explanation:
been transmitted.
bounced off .
been absorbed
Correct answer choice is :
C) Bounced off
Explanation:
Reflection is the difference in the path of a wavefront at an interface within two various media so that the wavefront returns into the tool from which it began. Current models involve the reflection of light, sound and water waves. Reflection is when light bounces off an object. If the cover is soft and shiny, like glass, water or bright metal, the light will reflect at the same point as it hit the cover.
Answer:Damge buildings that fall down after a earthquake also After shock
current
Answer:
Look at the picture
Explanation:
Answer:Correct ans is alternating current(AC CURRENT)
Explanation:Most houses in the U.S use alternative current for lights,fridges e.t.c that why when you turn of a switch in a room that particular rooms light goes off it doesn't affect the other rooms like what a direct current will do
Well how about direct current you Ask?
direct currents are also used in most homes examples are door alarms smoke detectors e.t.c
