1) The wave's period remains constant across different media
2) The wave's velocity varies depending on the medium it travels through
3) As a wave transitions between media, its speed, direction, and wavelength can change, while its frequency stays unchanged
Clarification:
1)
The period of a wave signifies the duration it takes for one full oscillation.
The wave's period is the inverse of its frequency:
where
T denotes the period
f is the frequency
The provided table illustrates that the frequency remains consistent across the three media; hence, the period is unchanged as it solely relies on frequency. We can compute it as we know that
f = 350 Hz
thus the period equals
2)
The velocity of a wave can be derived from the wave equation:
where
f indicates the frequency
is the wavelength
, resulting in a speed of
In the second medium,
, leading to a speed of
In the third medium,
, showing a speed of
As a result, we conclude that the wave's speed varies with the medium.

<pwhen a="" wave="" shifts="" from="" one="" medium="" to="" another="" the="" following="" occurs:="">- The wave's direction alters. Specifically, if the subsequent medium is of greater optical density, the wave bends towards the normal; conversely, it bends away if the second medium is of lesser optical density.
- The wave's speed is affected. The wave decelerates in media with higher optical density and accelerates in those with lower optical density.
- The wave's frequency remains unchanged.
- Ultimately, the wave's wavelength is modified. If moving into a medium of greater optical density, the wavelength decreases, while it increases in one of lower optical density.

x = v₀ cos θ t, y = y₀ + v₀ sin θ t - ½ g t2
Explanation:
This pertains to a projectile motion scenario. Here, we will express the equations for both the x and y dimensions.
Now, we will apply trigonometry to determine the initial velocity components.
sin θ = / v₀
cos θ = v₀ₓ / v₀
v_{y} = v_{oy} sin θ
v₀ₓ = v₀ cos θ
Next, let's formulate the equations of motion.
X axis
x = v₀ₓ t
x = v₀ cos θ t
vₓ = v₀ cos θ
Y axis
y = y₀ + t - ½ g t2
y = y₀ + v₀ sin θ t - ½ g t2
v_{y} = v₀ - g t
v_{y} = v₀ sin θ - gt
= v_{oy}^2 sin² θ - 2 g y
It is evident that the major distinction lies in the fact that in an inclined launch compared to a horizontal one, the velocity comprises different components
