The material in which a wave travels is called a medium. Hope this helps!
To solve this question, we use the wave equation which is:
C=f*λ
where:
C is the speed;
f is the frequency;
λ is the wavelength
So in this case, plugging in our values in the problem. This will give us:
C = 261.6Hz × 1.31m
= 342.696 m/s is the answer.

wave changes its path from its initial direction so this phenomenon is known as Refraction of wave
Explanation:
When wave travels from one medium to other medium the due to change in the speed of the wave propagation it deviates from its initial path.
The deviation of the wave from its initial path is known as refraction of wave
Here we can see that wave incident on medium 1 with some angle with the boundary
Then it enters into other medium and then travels in other direction
So here wave changes its path from its initial direction so this phenomenon is known as Refraction of wave
4.266 m is the radius of the circular path the electron follows.
Given
Speed of electron (v) = 7.5 × 10⁶ m/s
Earth's Magnetic Field (B) = 1 × 10⁻⁵ T
We already know that
Mass of electron (m) = 9.1 × 10⁻³¹ kg
Charge on electron (q) = 1.6 × 10⁻¹⁹ C
According to the formula
Radius of circular path(r) = mass on electron × speed/ Charge × Magnetic field
Radius of circular path(r) = m × v/q × B
Put the values into the formula
r = 9.1 × 10⁻³¹ × 7.5 × 10⁶/ 1.6 × 10⁻¹⁹ × 10⁻⁵
On solving, we get
r = 4.266 m
Hence, 4.266 m is the radius of the circular path the electron follows.

Yes, yes, go on ! The nearest star to us that's outside of our solar system
is 4.2 light years away. So when we see that star, we're not seeing it as
it is, we're seeing it as it was 4.2 years ago. And all of the other stars
are much farther away from us than that one is. We have detected
galaxies that we're not seeing as they are now, we're seeing them as
they were 13 billion years ago !
The moon is about 240,000 miles away from us. When we look at the
moon, we're not seeing it as it is, we're seeing it as it was 1.3 seconds ago.
The refrigerator in your kitchen is about 12 feet from you. So when you
look at the refrigerator, you're not seeing it as it is. You're seeing it as it
was 0.0000000122 second ago.
It takes TIME for light to travel from one place to another.
