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 electrons

with other businesses rather than the end user. There are many different types of industry‚ but most of them can be placed into two categories Light and Heavy industry. These two industries are very similar in some respects and very different in other ways‚ however they both have a common purpose of producing and manufacturing goods. Opposite to light are heavy industries‚ which refer to large-scale industries. The industries that are categorised as heavy include manufactures of mass transport

Refraction of light in water Refraction is the change in direction of a wave due to a change in its transmission medium. Due to change of medium‚ the phase velocity of the wave is changed but its frequency remains constant. This is most commonly observed when a wave passes from one medium to another at any angle other than 90° or 0°. Refraction of light is the most commonly observed phenomenon‚ When light travels from air into water‚ it slows down‚ causing it to change direction slightly. This

Isaac Newton (~1665) made up a particle model of light to explain many of the known behaviours of light at that time

How Technology is affecting our society. Is technology negatively affecting our society? There are many reasons it helps us positively‚ but is outnumbered by the reasons it hurts us. We need to find a way to fix this problem of ours that has hurt us in so many ways. One of the biggest ways that technology negatively affects society is making our society more obese and overweight. How? With technology taking over our lives people are being way less active and not getting the right amount of exercise
