Rearrange the jumbled

letters to form the term

being described.

Radio waves Microwaves Infrared Visible Light

Light travels in waves. It has several

properties like 1. ____ which refers

to the number of one complete wave

cycle in one second.

Energy Frequency Higher Greater Lesser Lower Wavelength Longer Shorter

Lastly, the amount of 3. _______the

wave carries, the higher the frequency

of the light wave, the more energy it

carries.

Energy Frequency Higher Greater Lesser Lower Wavelength Longer Shorter

The higher the frequency, the shorter the 4. ______. Energy Frequency Higher Greater Lesser Lower Wavelength Longer Shorter

The electromagnetic wave that carries greater amount of energy means it has higher 6. _______ Energy Frequency Higher Greater Lesser Lower Wavelength Longer Shorter

and if the Electromagnetic wave

have 7. _______ energy, it means it

has lower frequency.

Energy Frequency Higher Greater Lesser Lower Wavelength Longer Shorter

Several studies on low-frequency EMFs suggest these energy fields may cause various neurological and psychiatric problems in people. Studies found a link between EMF exposure and changes in human nerve function throughout the body, affecting things like sleep and mood. According to the latest research, EMFs are unlikely to cause any adverse health effects. You should feel safe using your cell phones, and appliances.

Closure: Suggest ways on how you can be protected with EMF’s exposure and be prevented from any adverse health effects.

2. How does an increase in frequency affect electromagnetic waves? A. Energy carried by the wave increases. B. Wavelength decreases. C. both A and B D. neither A nor B

3. What happens to the frequency and wavelength if the energy of the wave decreases? A. wavelength increases, frequency increases B. wavelength increases, frequency decreases C. wavelength decreases, frequency decreases D. wavelength decreases, frequency increases

5. What color in the visible spectrum

carries the highest energy?

A. red C. violet

B. blue D. orange
