<span>The relationship between wavelength, frequency and energy of Electromagnetic Radiation is given by
E = hf = hc/lamba -------(1)
So from (1) there's a linear relationship between E and f. The higher the frequency, f, the higher the energy E.
Also from (1) it is obvious that the lower the wavelength, lambda, the higher the energy, E.
This means the answer is D.</span>

Delilah: 170J/30s = 5.66 W
Adam: 260J/20s = 13 W
The speed of sound on planet is 210 m/s.

What is Oscillation?</h3>
Oscillation is the repeating or periodic change of a quantity around a central value or between two or more states, often in time. Alternating current and a swinging pendulum are two common examples of oscillation.
There are 3 main types of Oscillation –
- Free
- damped
- forced oscillation
f = frequency = 600 Hz
lambda = wavelength = 35 cm = 0.35 m
Now,
V = speed = f × lambda = 210 m/s
Hence, speed of sound on planet is 210 m/s.
