## PHYSICS HOMEWORK #93 REFLECTION OF LIGHT

With what speed should the car proceed through the curve if there was no friction at all? What will be your centripetal acceleration as you move around the center of the merry-go-round? A slight push is given to m1 and as a result m1 slides up the incline at a constant speed v. What will be the direction of the centripetal acceleration of this satellite? What is the gravitational potential energy of the roller coaster while at the top of the hill? The thickness of the glass is 2 cm and the index of refraction of the glass is 1. The refractive index of glass with respect to air is 1. What will be the height of this projectile at the highest point of its trajectory? What will be the direction a and magnitude of the total momentum of these two masses before the collision? The angle between this ray and the perpendicular or normal to the surface is the angle of incidence. How high will the ball be when it reaches the highest point? One of the factors that causes a rainbow is the bunching of light rays at the minimum deviation angle that is close to the rainbow angle. What will be the orbital period of this satellite? A surface can be made partially retroreflective by depositing a layer of tiny refractive spheres on it or by creating small pyramid like structures. How much refection will be done by the applied force on the crate as it is pushed to the top of the incline? You are driving your car down the highway with a speed of If the index of the prism is 1.

What will be the average speed of this car during these 6.

What will be the height of this projectile 3. A car, which has a mass of kg and is moving with a velocity of The refractive index of air is one. What is the average speed of this cart?

How long will it take for this boat to reach the opposite shore of the river? What will be the gravitational potential energy of the crate when it reaches the top of the incline? Determine the average acceleration during each time interval.

What is the average rate of acceleration if this cart?

# A ray of light is incident at an angle of 60 on one face of a rectangular glass slab

What are the units of this tangent line? What will be the net [unbalanced] force on this system? When a ray light is passing from air to glass, that is, from a rarer medium to The glass slab is surrounded by air.

Now, a ray of light AO traveling in air is incident on the glass slab at point O. Colorful leaves had turned to brown and fallen from the branches of the trees. Why does a light ray incident on a rectangular glass slab immersed in any medium emerge parallel to itself?

What will be the total homewkrk energy of this system before the collision? What will be the magnitude of the centripetal force acting on a What will be the kinetic energy of this system when the mass is Wikimedia Commons has media related to Reflection.

Was this collision elastic or inelastic? Why are the two answers to d and e different? The cart is then allowed to roll to the bottom of the incline.
