Wave Model of Light
Question | Answer |
---|---|
Wave | It is a disturbance or movement that transfers energy through matter or space, without causing any permanent displacement |
Energy | It is the capacity to apply a force over a distance. |
Force | It is a push or a pull on an object. |
Crest | It is the highest point on a wave. |
Trough | It is the lowest point on a wave |
Wavelength | It is the distance, in metres, for one complete cycle of the wave. |
Amplitude | It is the height of a wave crest or depth of a trough, as measured from its rest position. |
_______________ the amplitude, greater the energy transported | LARGER the amplitude, greater the energy transported |
_______________the amplitude, lesser the energy transported | SMALLER the amplitude, lesser the energy transported |
Light waves with larger amplitude will carry more energy and will be very _____________________ | Light waves with smaller amplitudes will carry less energy and will be very BRIGHT |
Light waves with smaller amplitudes will carry less energy and will be _________ | Light waves with smaller amplitudes will carry less energy and will be DIM |
________________________ is the number of repetitive motions, or oscillations , that occur in a given time | FREQUENCY is the number of repetitive motions, or oscillations , that occur in a given time |
Frequency is usually measured in __________ | Frequency is usually measured in HERTZ (Hz). |
Low Frequency- ___________wavelength | Low Frequency- LARGER wavelength |
High Frequency- __________ wavelength | High Frequency- SMALLER wavelength |
Frequency can be calculated using the following equation: | frequency = cycles/seconds |
Transverse wave | For this type of wave matter in the medium moves perpendicular to direction of the wave. |
Compression wave . | For this type of wave matter in the medium moves parallel to direction of the wave |
Transverse wave | Ocean waves |
Compression wave | Sound waves |
