Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. What is the BEST explanation of the relationship between wavelength and wave energy?
Answers
Answer : There exist an inverse relationship between the wavelength and the energy of the wave.
Explanation :
Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells.
The energy of a wave is given by the following relation :
So, it is clear that relation between the wavelength and the energy of the wave is inverse.
Higher the wavelength, least will be the energy of the wave.
The shorter the wavelength, the higher the frequency and the higher the energy.

A mass of 1.0 kg is initially held in place on a ramp of angle 45o at height of 20. meters above the ground. The mass is released and slides to the bottom of the ramp (h=0). There is friction between the mass and the ramp. At the bottom of the ramp, the object has a speed of 10. m/s. The thermal energy was generated by the friction as the mass slides down the ramp is closest to which value?

Answer;
The component waves have different frequencies.
Explanation;
-When two periodic waves meet, their amplitudes add (by principle of superposition) and the resulting disturbance can be either reinforced (constructive interference) or eliminated (destructive interference) .
-The magnitudes of reinforcement usually really dependent on the number of frequencies and interference is usually caused due to the difference in frequencies. Therefore, we can conclude that if the frequencies are different and causing interference, the reinforcement will also different.

What is vector quantity?
A physical quantity that has both directions and magnitude is referred to as a vector quantity.
A lowercase letter with a "hat" circumflex, such as "û," is used to denote a vector with a magnitude equal to one. This type of vector is known as a unit vector.
Let's learn vector addition and subtraction after first learning what a vector is. The simple arithmetic principles are not followed when adding or subtracting vector values. The addition and subtraction of vectors are conducted in accordance with a unique set of guidelines.
Given:
Force F₁ = 60 Newton east
Force F₂ = 80 Newton north
The resultant of the force is = √((60)² + (80)²) Newton = 100 Newton.
The direction of the force is = tan⁻¹(60/80) = 36.90°
