Mathematically, to compute for the wavelength, λ, we have
where v is the velocity and f is the frequency.
As we can see here, given that velocity is constant, wavelength increases as frequency decreases. This shows that wavelength is inversely proportional to frequency.
Answer: Wavelength and frequency are inversely related to each other.
Answer:
The maximum height above its initial position is:
Explanation:
Using momentum conservation:
(1)
Where:
- m(b) is the mass of the bullet
- m(B) is the mass of the block
- v(ib) is the initial velocity of the bullet
- v(fb) is the final velocity of the bullet
- v(fB) is the final velocity of the block
Let's find v(fb) using equation (1)
We need to find the maximum height, it means that all kinetic energy converts into gravitational potential energy.
I hope it helps you!

Answer:
b) bend away from the normal
Explanation:
According to snell's law , if i be the angle of incidence and r be the angle of refraction
sin i / sin r = 1.33 / 2.42
sin i / sin r = .55
Hence sin r > sin i
r > i
In other words angle of refraction will be more than angle of incidence . So, the ray will bend away from the normal .
