The reason for which the electrons left in the metals in an ordinary room without undergoing photoelectric effect.

Expert Solution & Answer

Answer to Problem 1CQ

The threshold wavelength for photoelectric effect to take place is generally shorter than the wavelength of visible light. Moreover the coatings and impurity substances on the surface of the metal prevents the action of knocking out of electrons from the surface of the metal.

Explanation of Solution

In photoelectric effect, electrons are ejected from certain metallic surfaces as the electromagnetic radiation falls in it. The energy of the incident photon is utilized for two purposes in this process. One is to eject the electrons from the metal surface and the other is to provide kinetic energy to the ejected electron. The incident photons must have a threshold energy to knock out electrons from the metal surface. If the incident photons have wavelength higher than the threshold value, or frequency less than the threshold value, the knocking out of electrons will not occur.

In an ordinary room atmosphere, the ambient light is in the visible range, which have wavelength higher than the threshold wavelength. Thus, the energy of the incident photons of visible spectrum cannot knock out electrons due to the lack of sufficient energy. Moreover, the oxide layers and other coatings on the surface of the metal often hinder the interaction of the incident light and the electrons in the metal surface. These are the reasons for which the electrons left in the metals in an ordinary room without undergoing photoelectric effect

Figure 8.14 shows a cube at rest and a small object heading toward it. (a) Describe the directions (angle 1) at which the small object can emerge after colliding elastically with the cube. How does 1 depend on b, the so-called impact parameter? Ignore any effects that might be due to rotation after the collision, and assume that the cube is much more massive than the small object. (b) Answer the same questions if the small object instead collides with a massive sphere.

2. A projectile is shot from a launcher at an angle 0,, with an initial velocity magnitude vo, from a point even with a tabletop. The projectile hits an apple atop a child's noggin (see Figure 1). The apple is a height y above the tabletop, and a horizontal distance x from the launcher. Set this up as a formal problem, and solve for x. That is, determine an expression for x in terms of only v₁, 0, y and g. Actually, this is quite a long expression. So, if you want, you can determine an expression for x in terms of v., 0., and time t, and determine another expression for timet (in terms of v., 0.,y and g) that you will solve and then substitute the value of t into the expression for x. Your final equation(s) will be called Equation 3 (and Equation 4).
