Explanation

• The average normal body temperature is generally accepted as 98.6°F (37°C).
• A temperature over 100.4°F (38°C) means you have a fever.

Additional Information:

• Hypothermia is the term used for temperature less than 36.50°C.
• Mild Pyrexia is the term used for temperature (99-100°F).
• Moderate Pyrexia is the term used for temperature (100-103°F).
• Severe Pyrexia is the term used for temperature (103-105°F).

Explanation

The energy of a photon is calculated using the formula E = hf, where:

• h = Planck’s constant
• f = frequency of the photon

This shows that photon energy is directly proportional to its frequency.

Explanation

• Refraction: Bending of light when it passes from one medium to another.
• A prism bends light at different angles depending on wavelength.
• This separation of colors is called dispersion, forming a spectrum.
• Visible spectrum colors: Red, Orange, Yellow, Green, Blue, Indigo, Violet (ROYGBIV).
