The image is virtual and smaller than the object is a
description of an image that can be produced by a concave lens.
To add, concave lenses<span> are thinner at the middle. Rays of light that pass
through the lens are spread
out (they diverge). It is a type of diverging lens.</span>
To solve the problem it is necessary to apply the conservation equations for the moment, specifically for collision. In addition to that, the concepts of vector velocity are necessary, in which the components are obtained and if the total magnitude is necessary.
Conservation of Momentum equation is given by,
We need to find the speed 3, therefore by readjusting the equation we have,
Therefore the components of the velocity would be,
Answer:
3.71 eV
Explanation:
λ = Wavelength of light = 224 nm = 224 x 10⁻⁹ m
c = speed of electromagnetic wave = 3 x 10⁸ m/s
V₀ = stopping potential = 1.84 volts
W₀ = Work function of the metal = ?
Using the equation
= 5.94 x 10⁻¹⁹
= 3.71 eV
