Pencil in glass of water. Refraction is the bending of light rays when they cross an interface between two materials with different refractive indices. For example, when light passes from air into the water at an angle, the light ray will bend toward the normal to the surface.
Physical Science Thank you for your input. Define angle of incidence. How does it relate to the efficiency of a solar cell? Is this a linear or non-linear relationship? How can solar cells be optimized with respect to the angle of incidence? What are the independent variables in this experiment? What are the constants?
How does a solar cell work? Solar cells convert sunlight into electrical energy. Different types of solar cells have varying degrees of efficiency and cost.
Since solar cells are expensive, their efficiency can be bolstered by mounting them to devices that move them so that they are always at the optimal angle of incidence with respect to energy output.
In this experiment, students will determine the optimal angle for energy output. Resistors are often sold in packs of five. This line will be the new top face of the cube.
Saw along the line using a power saw in a wood shop. Alternatively, if you have a set of small cardboard boxes, cut one side of the box so that it is free on three sides and hinged on the bottom.
Bend the side so that stands at the correct angle and tape into place. Cut the two adjacent sides so that they are flush with the side you taped into place. After you prepared the cubes, you will have two cubes left over that do not require cutting.
Mount the solar cell to the top face of each of five blocks with double-sided tape. With respect to the sixth and seventh blocks, mount the solar cell on the top and side of the block respectively. If the solar cell is on the top of the block, it will form a degree angle with the sides.
If the solar cell is on the bottom of the block it will form a 0 degree angle. Couple a ohm resister to both ends of each solar cell on every block. Move your cubes so they are outdoors.
Conduct this experiment when the sun is directly overhead. In the first cube, couple one of the alligator clips on the ammeter to one of the clips on voltmeter. Couple the free clip of the ammeter to the resistor. Couple the free clip of the voltmeter to the other side of the resistor.
The ammeter and voltmeter should be reading the voltage and current in the circuit across the resistor. Record the volts and amps in the circuit.
Repeat step 5 for each of the blocks. Calculate the power measured in watts for every circuit. Create a data table showing the volts, watts and amps of every cube. The x-axis should represent power in watts and the y-axis should represent the angle of incidence.
Is there a relationship between the two? Is it linear or non-linear? Angle of incidence; Solar cell; Photovoltaic effect; Dependent vs.
A Green Energy Guide. New Society Publishers In case the angle of incidence is perpendicular to the glass surface, the fraction of reflected light is given by the reflection coefficient or reflectance, R, with n o being the refractive index of the medium the light is coming from (e.g., air with n ≈ 1) and n G being the refractive index of the glass.
This paper explores how the efficiency of the cell changes as the light angle of incidence changes by using experimental data and estimation of measurement errors to develop a model to predict cell performance at various angles of light incidence.

The angle of incidence in the more refractive medium must be larger than the critical angle. The critical angle refers to an angle of incidence that produces a corresponding emerging ray that has an angle .
In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The ray can be formed by any wave: optical, acoustic, microwave, X-ray and so on.
angle of incidence or decalage relative to the stab at zero, the wing will generate a balance of upward lift to support the airplane’s weight And since the lift is provided by means of incidence the airplane’s (as opposed to using elevator trim), changes in airspeed.
