Frequency f =5×10^9Hz
Speed of radio waves=speed of light c =3×10^8m/s
Wavelength λ = c/f
= 3×10^8/5×10^9
= 0.06m
She remains the only person to be honored for accomplishments in two separate sciences. Curie received the Nobel Prize in Physics in 1903, <u>along with her husband and Henri Becquerel, </u>for their work on radioactivity.
<h3>What did Marie Curie discover?</h3>
Relentless regardless of a vocation of truly requesting and at last lethal work, she found polonium and radium, supported the utilization of radiation in medication and essentially changed how we might interpret radioactivity. Curie was conceived Marya Skłodowska in 1867 in Warsaw.
- Curie was the first person to win two Nobel Prizes.
- She managed it all without a fancy lab.
- Nobel Prizes were a family affair.
- Curie was the first female professor at Sorbonne University.
- Curie is buried in the Panthéon in Paris.

Answer:
The angle of reflection is "60°".
Explanation:
The given values are:
Light from monochromatic source,
= 560 nm
Angle of incidence,
= 60°
Surface of fused quartz (n),
= 1.56
Whenever a light ray was indeed occurring at a flat surface, it should be the law or concept of reflection which contains this same rays of light, the reflected ray as well as the "normal" ray at either the mirror surface.
According to the above law,
⇒ 
then,
⇒ 
The energy carried by a photon is equal to
(Planck's Konstant) times (the frequency of the photon) .
Planck's konstant is 6.626 x 10⁻³⁴ m²-kg/s (rounded)
