As the speed of wave decreases, the wavelength of the wave decreases.
<h3>Refraction</h3>
We know that as a wave travels from one medium to another its speed decreases depending on if the first medium is less dense than the second medium or increases depending on if the first medium is more dense than the second medium. This is known as refraction
Now, we know that the speed of a wave v = fλ where
- f = frequency and
- λ = wavelength. Since f is constant, v ∝ λ.
The ratio of the speed in medium one to speed in medium two is called the refractive index of medium 1 to 2.
<h3>Explaining the diagram</h3>
From the diagram, we see that the wavelength in medium 1 is longer than that in medium 2. Since wavelength and speed are proportional, so the speed in medium 1 is also greater than the speed in medium 2.
So, As the speed of wave decreases, the wavelength of the wave decreases.

Water can contain dillute chemical solutions that can dissolve rock such as hydrochloric acid working against limestone
Answer:
C. parabolic Curve
Explanation:
The trajectory of a projectile motion is parabolic.
If a ball is thrown at angle of 45° to the horizontal then it will follow a parabolic curve during its motion as its a projectile motion. The other options are incorrect as sine curve is a periodic type of curve. linear curve and tangential curve are also out of place.So option C is correct

Answer: The planet, named after the Roman goddess of art and beauty, can actually be bright enough to cast shadows on a moonless night. It appears so close to the sun because its orbital radius is smaller than the Earth's, and because it also moves faster than Earth, its orbital period is shorter.
