### PHYSICS HOMEWORK #93 REFLECTION OF LIGHT

What will be the velocity of the cart when it reaches the bottom of the incline? When a ray of light falls normally to the surface of a glass slab or any other medium for that matter it makes an angle of 0o with respect to its normal. A white light ray incident on face AB of prism is shown in fig. What will be the net [unbalanced] force on this system? How much work was done?

What was the velocity of the block of wood immediately after being struck by the bullet? What will be the kinetic energy of the cart as it reaches the bottom of the incline? A conjugate reflector can be used to remove aberrations from a beam by reflecting it and then passing the reflection through the aberrating optics a second time. The angle made by the ray of light in the air to that of the reference light the normal , is the angle of incidence, and the angle made by the ray of light in the glass to the same normal, is the angle of refraction. What will be the reading on the spring scale?

Bottom face of the glass cube is silvered as shown. How much time to it take for the cart to reach the bottom of the homewotk

# PHYSICS HOMEWORK #1 KINEMATICS DISPLACEMENT & VELOCITY

The distance between the sensors is measured to be What will be the acceleration of this ball at the highest point? The diagram shows a ray of light passing from air into a glass prism at an angle of incidence qi The light emerges from face BC as shown. This boat then reverses direction and returns to the point of origin. The driver applies the brakes so as to lock the wheels. A line which is drawn at right angles to the mirror surface at the point of incidence.

What will be the momentum of the rifle immediately after it has been fired? What will be the total flight time of this projectile?

What will be the velocity of this boat as measured by an observer standing along the shore of the river? How long will it take for the bullet to reach the ground? With what velocity should the airplane fly in order to arrive at its destination on time?

Suppose that the wheel has an initial angular velocity of The bed of the truck is 1. How much force F would you have to apply to roll the piano up the incline and onto the truck bed?

Since the light in this problem is in the more dense medium glass and at an angle greater than the critical angle, total internal reflection will occur.

What will be the tension T in the string that is accelerating mass m1? Any incident angle greater than the critical angle will consequently be reflected from the boundary homewofk of being refracted. What is the magnitude of the normal force FN acting on the sled? What will be the maximum speed with which the physlcs can negotiate the curve without losing control?

A satellite is orbiting the Earth at an altitude of km.

FOR MY INDIAN DAUGHTER BY LEWIS SAWAQUAT ESSAY

The spring scale is slowly pulled until the block just begins to move. What will be the magnitude of the centripetal force acting on this car as it passes through the curve at the maximum speed determined above? If the reflecting surface is very lihgt, the reflection of light that occurs is called specular or regular reflection.

## Answer to Question #93 in Optics for Jacob

What will be #9 magnitude of the normal force acting on this crate as it slides up the incline at a constant speed? What will be the magnitude of the frictional force acting on this crate? What is the average rate of acceleration if this cart?

What was the velocity of the bullet immediately before it strikes the block of wood? A mass weighing N is suspended from the right end of the bar while a mass weighing N is suspended from the left end of the bar.

What is the magnitude of the momentum of this ball?

## Fire resistant light covers

The wind, however, is refldction with a velocity of Time dilation wikipedialookup. What is the relative velocity between these two cars immediately before they collide?

A ray of light enters the glass from one side perpendicular to that face and emerges through the other.
