Question:
The following topics are involved in this integrated concepts worked example:
A 550-nm photon (visible light) is absorbed by a 1.00-μg particle of dust in outer space.
(a) Find the momentum of such a photon.
(b) What is the recoil velocity of the particle of dust, assuming it is initially at rest?
Strategy Step 1
To solve an integrated-concept problem, such as those following this example, we must first identify the physical principles involved and identify the chapters in which they are found. Part (a) of this example asks for the momentum of a photon, a topic of the present chapter. Part (b) considers recoil following a collision, a topic of Linear Momentum and Collisions.
Strategy Step 2
The following solutions to each part of the example illustrate how specific problem-solving strategies are applied. These involve identifying knowns and unknowns, checking to see if the answer is reasonable, and so on.
