ELECTROMAGNETIC WAVES

                            ELECTROMAGNETIC WAVES  

TYPES OF ELECTROMAGNETIC WAVES

1. GAMMA RAYS

2. X-RAYS

3. ULTRA-VIOLET RAYS

4., VISIBLE LIGHT

5. MICROWAVES

6. RADIOWVES

7. INFRARED WAVES

USES OF ELECTROMAGNETIC WAVES:-

1. GAMMA RAYS

#  GAMMA RAYS ARE USED IN THE MEDICAL TREATMENT (RADIOTHERAPY) TREATMENT OF CANCER.

# IN THE FOOD INDUSTRY TO KILL MICROORGANISMS.

2. X-RAYS

# IN THE STUDY OF STRUCTURES AND COMPOSITION OF ATOM.

# IN THE MEDICAL DIAGNOSE ( DETECT FRACTURES).

3. ULTRA-VIOLET RAYS

# FOR STERILIZING SURGICAL INSTRUMENTS.

# TO PRESERVE FOODSTUFF.

# IN THE STUDT OF MOLECULAR STRUCTURE.

4. VISIBLE LIGHT

#  IT IS USED TO HELP IN THE DESIGNING OF MICROSCOPES AND TELESCOPES.

# IT HELP TO MAKE HUMAN BEING TO SEE THE OBJECTS.

# IT IS THE PART OF THE ELECTROMAGNETIC SPECTRUM WHICH IS VISIBLE.

5. MICRO WAVES

# IN MICROWAVE OVENS FOR COOKING PURPOSES

# IN RADAR SYSTEMS FOR AIRCRAFT DETECTION.

6. RADIO WAVES

# IN TELEVISION AND RADIO BROADCASTING

# IN SKY WAY COMMUNICATION

# UHF (BAND) IS USED IN CELLULAR PHONES.

7. INFRARED WAVES

# IN SOLAR WATER HEATERS AND COOKERS

# IN GREEN HOUSE EFFECT TO KEEP THE LANTS WARM.

PROPERTIES OF ELECTROMAGNETIC WAVES:-

1. GAMMA RAYS

#GAMMA RAYS HAVE HIGH PENETRATION POWER

# IT CAN NOT BE DEFLECTED BY ELECTRIC AND MAGNETIC FIELDS.

2. X-RAYS

# X-RAYS CAN UNDERGO ALL THE PHENOMENA LIKE REFLECTION, REFRACTION, INTERFERENCE, AND DIFFRACTIONS.

# IONISE THE GAS THROUGH WHICH THEY PASS.

3. ULTRA-VIOLET RAYS

# U.V. RAYS CAN UNDERGO ALL THE PHENOMENA LIKE REFLECTION, REFRACTION, INTERFERENCE ETC.

# THEY ARE TRANSVERSE WAVES AND TRAVEL WITH THE SPEED OF LIGHT.

4. VISIBLE LIGHT

# LIGHT OBEYS ALL THE LAWS OF REFLECTION, REFRACTION, INTERFERENCE, AND DIFFRACTION IN THE BRANCH OF PHYSICS CALLED OPTICS.

# THEY ARE TRANSVERSE LIGHT AND TRAVEL WITH SPEED.

5. MICROWAVES

    THEY ARE NO DIFFERENCE BETWEEN VISIBLE LIGHT AND MICROWAVES.

# LIGHT OBEYS ALL THE LAWS OF REFLECTION, REFRACTION, INTERFERENCE, AND DIFFRACTION IN THE BRANCH OF PHYSICS CALLED OPTICS.

# THEY ARE TRANSVERSE LIGHT AND TRAVEL WITH SPEED.

6. RADIOWAVES

  THEY ARE NO DIFFERENCE BETWEEN VISIBLE LIGHT AND RADIO WAVES.

# LIGHT OBEYS ALL THE LAWS OF REFLECTION, REFRACTION, INTERFERENCE, AND DIFFRACTION IN THE BRANCH OF PHYSICS CALLED OPTICS.

# THEY ARE TRANSVERSE LIGHT AND TRAVEL WITH SPEED.

7. INFRARED WAVES

THERE IS NO DIFFERENCE BETWEEN VISIBLE LIGHT, INFRARED WAVES, MICROWAVES, AND RADIO WAVES. THE ONLY DIFFERENCE BETWEEN THEM IS THEIR USES.

# LIGHT OBEYS ALL THE LAWS OF REFLECTION, REFRACTION, INTERFERENCE, AND DIFFRACTION IN THE BRANCH OF PHYSICS CALLED OPTICS.

# THEY ARE TRANSVERSE LIGHT AND TRAVEL WITH SPEED.
