Assessment ISA (PU 2.5) Light Dependent Resistors (Section 1) 1. Write down your hypothesis. Explain why you made this hypothesis. Hypothesis: When it is day there is more light hitting the LDR and so its resistance decreases and the light turns off. When it is night there is less light so the LDR has higher resistance and the light turns on. Explanation: When light shines on a Light Dependent Resistor‚ electrons are released and the current can get larger. So as the light intensity increases‚ more

The Compound Light Microscope Commonly binocular (two eyepieces)‚ the compound light microscope‚ combines the power of lenses and light to enlarge the subject being viewed. Typically‚ the eyepiece itself allows for 10X or 15X magnification and when combined with the three or four objective lenses‚ which can be rotated into the field of view‚ produce higher magnification to a maximum of around 1000X generally. The compound light microscope is popular among botanists for studying plant cells‚ in

LIGHT EMITTING DIODES Light Emitting Diodes are electronic components that use the flow of electrons to excite materials into emitting photons of light. A diode is a basic electronic component that allows electricity to flow one way only. The discovery of "light emitting" diodes we believe was an accident sometime around 1907 when a diode in an early radio transmitter was noticed to glow when in use. Incandescent bulbs use resistance in a filament to impede the flow of electricity‚ heating

Isn’t it interesting how the use of light can be both an enhancement as well as a loss? “Light the Way” refers to helping one’s sight‚ whereas “blinded by the light” refers to light shining straight in one’s face‚ resulting in restricted vision. When Pablo Neruda says “the world is a glass overflowing with water” in “Ode to Enchanted Light” he means that the world is still full of hope. “Ode to enchanted light” by Pablo Neruda as well as “Sleeping in the forest” by Mary Oliver are poems that carry

Shakespeare’s play Macbeth is chock-full of different examples of imagery‚ many of which reappear throughout the entire play. Three major patterns of imagery include light versus darkness‚ clothing‚ and blood. The first example‚ light and darkness‚ is the most obvious and recurrent. In Shakespeare’s writing‚ light is associated with life‚ God‚ and acts of kindness‚ while darkness foretells death and evil. In the first act‚ Lady Macbeth asks for night to come so that her “keen knife see not the wound
