What are constructive interference and destructive interference?
when two waves superimposed on each other in the same phase (phase diff is 0), then the resultant amplitude becomes the sum of the amplitudes of the two waves. This type of interference is called constructive interference. on the other hand, when two waves superimposed on each other in the opposit phase (phase diff is 180 degree), then the resultant amplitude becomes the difference of the amplitudes of the two waves. This type of interference is called destructive interference.
What direction do waves changes?
Waves change direction when they encounter a change in medium or boundary that causes them to refract or reflect. Refraction occurs when waves change speed as they move from one medium to another, causing them to bend. Reflection occurs when waves bounce off a boundary, changing direction.
Which phenomenon occurs when one wave is superimposed on another?
Beats are formed. The number of beats heard in one second will be equal to the difference in frequencies. If the difference is 4, then 4 beats will be heard in one second. If 1/4 is the difference in frequencies then 1 beat will be heard in every 4 second.
Is it possible for two identical waves travelling in the soame direction along a string to give rise to a stationary wave?
Yes, if two identical waves with the same amplitude and frequency but moving in opposite directions along a string interfere constructively, they will create a stationary wave pattern with nodes (points of no displacement) and antinodes (points of maximum displacement). This phenomenon occurs due to the superposition of the two waves.
Which wave refracts?
All types of waves can refract, including light waves, sound waves, and seismic waves. Refraction occurs when a wave changes direction as it passes from one medium to another at an angle, due to a change in the wave's speed.

Which wave property changes when two waves interfere in the same medium?
The amplitude of the waves can change when two waves interfere in the same medium. Constructive interference occurs when the amplitudes add up, resulting in a larger amplitude, while destructive interference occurs when the amplitudes cancel out, resulting in a smaller amplitude.
What is the identical light waves in a phase called?
Identical light waves in phase are called coherent light waves. Coherent waves have a constant phase difference between them, which allows for constructive interference and the formation of interference patterns.
How does diffraction occur with electromagnetic waves?
Diffraction of electromagnetic waves occurs when the waves encounter an obstacle or aperture that is comparable in size to the wavelength of the waves. This causes the waves to bend around the obstacle or spread out after passing through the aperture, resulting in interference patterns and changes in the wave's direction and intensity.
Reflection occurs when a wave does what?
Reflection occurs when a wave encounters a boundary or obstacle and bounces back in the opposite direction. This can happen with various types of waves, including sound waves, light waves, and water waves. Reflection is a fundamental principle in physics and is observed in many natural phenomena.
What waves occurs when the motion of the medium is parallel to the direction of the waves?
amplitude Longitudinal waves occurs when the motion of the medium. This is parallel to the direction of the wave.
What are the first waves to arrive when a earthquake occurs?
P waves
Explain diffraction and refraction How are they similar?
Diffraction is the bending of waves around obstacles and edges, demonstrating their wave nature. Refraction is the bending of waves as they pass from one medium to another, due to changes in their speed. Both phenomena involve the bending of waves, but diffraction occurs when waves encounter obstacles or openings, while refraction occurs when waves pass through different mediums.
