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.

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 .
