The energy carried per photon of light is inversely proportional to the wavelength of the light
The "quantum of electromagnetic radiation" is called a photon. It is, thus, the tiniest and most basic particle of electromagnetic radiation. A photon is a stable particle that has no mass and no electric charge. The concept of wave-particle duality holds true for this particle.
The distance between the two crests or troughs of the light wave is known as the wavelength of light. It is represented by the greek letter lambda 'λ'
A quantity is inversely proportional if it decreases when the related quantity is increased or vice versa. For example, frequency is inversely proportional to wavelength

Answer:
The answer is below
Explanation:
Momentum is used to measure the quantity of motion in an object. Momentum is the product of mass and velocity.
Momentum = mass * velocity
The principle of conservation of momentum states that momentum cannot be created or destroyed but can be transferred. Therefore the momentum before and after an action is equal.
Initial momentum = Final momentum
Let m be the mass of the diver, M be the mass of the raft, u be the initial velocity of the diver, U be the initial velocity of the raft, v be the final velocity of the diver and V be the final velocity of the raft.
m = 71 kg, M = 500 kg, v = 6 m/s
Initial both the raft and diver are at rest, hence u and U is zero, hence:
mu + MU = mv + MV
71(0) + 500(0) = 71(6) + 500(V)
0 = 426 + 500(V)
500(V) = -426
V = -426/500
V = -0.852 m/s
The type of waves used by bats are sound waves. Most of the species use their larynx to produce ultrasound waves in the frequency range of 20 to 200 kilohertz.
These sound waves are echoed, reflected, by surroundings, in this case food or prey. These reflections are received by the specialized receptor cells in the ears of bats. The reflections are analyzed by the brain to make an image.
Fun fact: The brain cells of bats are also specialized to better analyze the frequency of ultrasound used by the bat.
