Arrange the following electromagnetic radiations per quantum in the order of increasing energy: A Blue light B: Yellow light C:X-rays D:Radiowave

Options

A. A, B, D, C
B. C, A , B, D
C. B, A, D, C
D. D, B, A, C

Answer

To solve the problem of arranging the electromagnetic radiations in order of increasing energy, we will follow these steps:

### Step 1: Understand the relationship between energy and frequency
The energy of electromagnetic radiation is given by the formula:
\[ E = h \nu \]
where:
- \( E \) is the energy,
- \( h \) is Planck's constant, and
- \( \nu \) (nu) is the frequency of the radiation.

From this formula, we can see that energy is directly proportional to frequency. This means that higher frequency radiation has higher energy.

### Step 2: Identify the types of electromagnetic radiation given
The types of electromagnetic radiation provided in the question are:
- A: Blue light
- B: Yellow light
- C: X-rays
- D: Radiowave

### Step 3: Determine the frequency order of the given radiations
We need to arrange these types of radiation based on their frequency, from lowest to highest:
1. **Radiowave (D)** - has the lowest frequency.
2. **Yellow light (B)** - has a higher frequency than radiowaves but lower than blue light.
3. **Blue light (A)** - has a higher frequency than yellow light.
4. **X-rays (C)** - have the highest frequency among the given options.

### Step 4: Arrange the radiations in order of increasing energy
Now that we have established the order of frequency, we can arrange the radiations in order of increasing energy:
1. **Radiowave (D)** - lowest energy
2. **Yellow light (B)**
3. **Blue light (A)**
4. **X-rays (C)** - highest energy

Thus, the order of increasing energy is:
\[ D < B < A < C \]

### Final Answer
The correct order of electromagnetic radiations per quantum in the order of increasing energy is:
\[ D, B, A, C \]
