Standing waves are produced by periodic waves of?
The same amplitude and wavelength traveling in the same direction
If two transverse waves have the same wavelength the wave with the has the greatest wave speed.?
If two transverse waves have the same wavelength, the wave with the __________ has the greatest wave speed.
Which transmits more energy if two waves has same amplitude and same speed but differ in wavelength?
The wave with the shorter wavelength will transmit more energy than the one with the longer wavelength if two waves have the same amplitude and same speed but differ in wavelength. The energy transmitted by the shorter wavelength will normally be four times more than the energy transmitted by the longer wavelength.
How can two different types of waves have the same wavelength?
Yes, they can.
Can waves with different wavelength be coherent?
No. In order to be coherent, the light waves have to be in phase and stay in phase, and the only way for that to happen is for them to have the same wavelength and frequency.
What is the best definition of diffraction?
n.Change in the directions and intensities of a group of waves after passing by an obstacle or through an aperture whose size is approximately the same as the wavelength of the waves.Read more: diffraction
When a moves through an opening in a barrier it?
Bends and spreads out.When waves of any kind, sound, light electromagnetic radiation hit a gap in a barrier that is on the same scale as the wavelength then diffraction will occur. Diffraction is the bending of the wave and this appears as circular waves when we observe this effect with water.A common diffraction grating can be seen on a CD or DVD. The light spreads and we see this as different colours.

What is the speed of radio waves with a wavelegnth of 4.2m?
The speed of any electromagnetic waves (and that includes radio waves) in a vacuum is always the same - approximately 300,000 km/second. The wavelength is irrelevant.
Are waves with a shorter wavelength different from those with a longer wavelength?
No, they're all waves, they're all the same!
How the wavelength of waves traveling with the same speed would change if the waves increases?
The wavelength would decrease - in inverse proportion.
Does infred waves have the same wavelength as visible light waves?
Infrared radiation is not visible. Its wavelength is longer than red.
Standing waves are produced by periodic waves of?
The same amplitude and wavelength traveling in the same direction
If two transverse waves have the same wavelength the wave with the has the greatest wave speed.?
If two transverse waves have the same wavelength, the wave with the __________ has the greatest wave speed.
Diffraction is what?
Change in the directions and intensities of a group of waves after passing by an obstacle or through an aperture whose size is approximately the same as the wavelength of the wavesThe aperture, then, starts to act like a new source of waves.Subatomic particles which have dual behaviour ( particle-wave ), like electrons or photons, can also suffer diffraction.THE BENDING OF WAVESI am assuming you mean diffraction. A diffraction is a phenomenon that occurs when a wave passes through two slits and a pattern is observed a certain distance away from the slits. Because waves are unlike particles, when they go through a slit, they tend to spread out instead of going straight. When there are two slits and a wave is allowed to travel through it, it will "diffract" and display a pattern on an observatory wall.This diffraction is one of the main factors that proved Einstein wrong when he said light behaves like a particle.Waves have a tendency to spread as they propagate through a medium. As a result, when a wave encounters an obstacle, it spreads into the region behind the obstacle. This phenomenon is called diffraction. The amount of diffraction depends on the wavelength: The longer the wavelength, the greater is the spreading of the wave. Significant diffraction into the region behind the obstacle occurs only if the size of the obstacle is smaller than the wavelength. For example, a person sitting behind a pillar in an auditorium hears the performer because the long wavelength sound waves spread behind the pillar. But the view of the performance is obstructed because the wavelength of light is much smaller than the pillar, and, therefore, the light does not diffract into the region behind the pillar.Objects that are smaller than the wavelength do not produce a significant reflection. This too is due to diffraction. The wave simply diffracts around the small obstacle, much as flowing water spreads around a small stick.Both light waves and sound waves can be focused with curved reflectors and lenses. There is, however, a limit to the size of the focused spot. It can be shown that the diameter of the focused spot cannot be smaller than about λ/2. These properties of waves have important consequences in the process of hearing and seeing.
Which transmits more energy if two waves has same amplitude and same speed but differ in wavelength?
The wave with the shorter wavelength will transmit more energy than the one with the longer wavelength if two waves have the same amplitude and same speed but differ in wavelength. The energy transmitted by the shorter wavelength will normally be four times more than the energy transmitted by the longer wavelength.
How the constructive interference occurs?
coherent waves are waves of the same frequency (same wavelength) and constant phase difference.
