No, but it can result in standing waves where some points are stationary.

When a wave passes from a less dense medium to a denser one most of the wave energy is?
When a wave passes from a less dense medium to a denser one, most of the wave energy is answer is reflected FALSE
The formation of a standing wave requires?
Standing waves are formed when the reflected wave reinforces the initial wave at a resonant frequency. At other frequencies, the reflected wave tends to cancel out the initial wave. One example of a standing wave is when a guitar string is plucked. Due to the tension of the string, the length, and the mass, the string will vibrate at one frequency.
What the causes a maximum on a standing wave?
A standing wave pattern is a vibrational pattern created within a medium when the vibrational frequency of the source causes reflected waves from one end of the medium to interfere with incident waves from the source. This interference occurs in such a manner that specific points along the medium appear to be standing still. Because the observed wave pattern is characterized by points which appear to be standing still, the pattern is often called a standing wave pattern. Such patterns are only created within the medium at specific frequencies of vibration. These frequencies are known as harmonic frequencies, or merely harmonics. At any frequency other than a harmonic frequency, the interference of reflected and incident waves leads to a resulting disturbance of the medium which is irregular and non-repeating.
What is an example for a wave interaction?
Reflection and absorption...most likely a combination of the two. In reflection the wave bounces back off the barrier and, depending on the incident wave and how it matches in phase with the reflected wave, the reflected wave could be enhanced through constructive interference with the incident wave or degraded through destructive interference. In absorption, the energy from the incident wave is taken into the barrier material. This typically causes the barrier to vibrate indicating the energy it absorbed. A barrier is more likely to absorb the energy when its natural frequency is some harmonic of the incident wave.
The crests of one wave overlap the troughs of another wave?
it is possable for a crest to overlap a trough and they cancel each other out

Do you get a phase change of pi on reflection with denser medium in case of longitudinal waves?
This is a general property of waves. If you have waves reflecting off a clamped point (like waves running on a string that you pinch hard at one point), the waves get phase inverted. The reason is the principle of superposition and the condition that the amplitude at the clamped point is zero. The sum of the reflected and transmitted wave must be the amplitude of oscillation at all points, so that the reflected wave must be phase inverted to cancel the incoming wave. This property is continuous with the behavior of waves going from a less massive string to a more massive string. The reflection in this case has opposite phase, because the more massive string doesn't respond as quickly to the tension force, and the amplitude of oscillation at the contact point is less than the amplitude of the incoming wave. This means (by superposition) that the reflected wave must cancel part of the incoming wave, and it is phase reflected. When a wave goes from a more massive string to a less massive string, the less massive string responds with less force, so that the derivative at the oscillating end is flatter than it should be. This means that the reflected wave is reflected in phase with the incoming wave, so that the spatial derivative of the wave is cancelled, not the amplitude reduced. In optical materials of high density are analogous to strings with a higher density, hence the name. If you go into a material with low speed of light, the time derivative term in the wave-equation is suppressed, so that the field responds more sluggishly, the same way that a massive material responds more sluggishly to tension pulls. Since the eletric field response in these materials is reduced, the reflected wave is phase inverted to make the sum on the surface less, as is appropriate to match with the transmitted wave.
What is the angle between the incident and reflected rays when a ray of light is incident normally on a plane mirror?
if one is to define this question one will be aware that the normal is perpendicular to the surface and thus creates a angle of 90 degrees.
When light is reflected off of a smooth surface in how many ways is it reflected?
It is reflected in only one way: in a straight line and the direction such that the angle between the incident ray and the normal at the point of incidence is the same as the angle between the normal and the reflected ray, but on the opposite side of the normal.
Is it possible for one wave to cancel another wave and the combined amplitude became zero?
yes but no because waves don't crash into each other in the middle of the sea. P.S i am 12
Is it possible to have a longitudinal wave in stretched string?
yes, Its possible to have a longitudinal wave on a stretched string by stroking it along its length by a rosined cloth. However, in the wave motion of a stretched string ( tant string with fixed ends) wave (disturbance) produced at one fixed end travels along the length of the string and get reflected back at the other end. Since the original wave and the reflected wave have the same frequency and amplitude, they superimpose to produce stationary transverse disturbance.
