Red light has a typical wavelength of 7.0 × 10-7 m and frequency of 4.3 × 1014 Hz.
Which row in the table gives a typical wavelength and frequency for violet light?
| Wavelength | Frequency | |
|---|---|---|
| A | 4.0 × 10-7 m | 7.5 × 1014 Hz |
| B | 4.0 × 10-7 m | 2.5 × 1014 Hz |
| C | 9.5 × 10-7 m | 7.5 × 1014 Hz |
| D | 9.5 × 10-7 m | 2.5 × 1014 Hz |
Wavelength =4.0×10−7 m= 4.0 \times 10^{-7}\text{ m}=4.0×10−7 m, frequency =7.5×1014 Hz= 7.5 \times 10^{14}\text{ Hz}=7.5×1014 Hz
Wavelength =4.0×10−7 m= 4.0 \times 10^{-7}\text{ m}=4.0×10−7 m, frequency =2.5×1014 Hz= 2.5 \times 10^{14}\text{ Hz}=2.5×1014 Hz
Wavelength =9.5×10−7 m= 9.5 \times 10^{-7}\text{ m}=9.5×10−7 m, frequency =7.5×1014 Hz= 7.5 \times 10^{14}\text{ Hz}=7.5×1014 Hz
Wavelength =9.5×10−7 m= 9.5 \times 10^{-7}\text{ m}=9.5×10−7 m, frequency =2.5×1014 Hz= 2.5 \times 10^{14}\text{ Hz}=2.5×1014 Hz
