Explain How did the temperature of the bulb affect the spectra that were observed?

Relate the amount of energy to wavelength. Refraction Animation

Spectra Predict & Observe Do you think you will see emission or absorption spectra?

What do you think a spectra of a compound will look like? Explain Why did you see emission

spectra? Why did the spectra of water look like it did? Question 1 A wave has a low speed, but a high frequency.

What can be inferred about its wavelength? A. The distance a wave will vibrate from its resting point. B. The wavelength will be very long C. It depends on how fast the speed is D. The wavelength will be short

Answer 1 A wave has a low speed, but a high frequency. What can be inferred about its wavelength? A. The distance a wave will vibrate from its resting point.

B. The wavelength will be very long C. It depends on how fast the speed is D. The wavelength will be short Question 2 How is amplitude related to energy?

A. The larger the amplitude, the more energy a wave carries B. The larger the amplitude, the less energy a wave carries C. The shorter the amplitude, the more energy a wave carries

D. Amplitude is not related to energy Answer 2 How is amplitude related to energy? A. The larger the amplitude, the more energy a wave carries

B. The larger the amplitude, the less energy a wave carries C. The shorter the amplitude, the more energy a wave carries D. Amplitude is not related to energy
